Os pavimentos de vinil deformam-se devido \u00e0 falta de folgas de expans\u00e3o, humidade na base, altera\u00e7\u00f5es extremas de temperatura, m\u00e1 prepara\u00e7\u00e3o da base, cola errada ou falta de aclimata\u00e7\u00e3o. Pode evitar esta situa\u00e7\u00e3o deixando intervalos de $1\/4$ polegadas, testando a humidade, aclimatando as t\u00e1buas durante 48 horas e mantendo n\u00edveis est\u00e1veis de humidade no interior.<\/strong><\/p>\n

Como engenheiro de f\u00e1brica que projecta linhas de produ\u00e7\u00e3o de pavimentos vin\u00edlicos, vejo estes problemas constantemente. As pranchas e os ladrilhos de vinil de luxo (LVP) s\u00e3o concebidos para serem altamente dur\u00e1veis e resistentes \u00e0 \u00e1gua, mas n\u00e3o s\u00e3o completamente indestrut\u00edveis. Quando fabricamos pavimentos de vinil, misturamos cloreto de polivinilo (PVC) com estabilizadores e p\u00f3 de calc\u00e1rio para criar um n\u00facleo r\u00edgido ou flex\u00edvel. Este material comporta-se de forma previs\u00edvel em condi\u00e7\u00f5es controladas, mas reage fortemente \u00e0s for\u00e7as f\u00edsicas e \u00e0s altera\u00e7\u00f5es ambientais depois de instalado em sua casa. Se o ambiente circundante mudar demasiado depressa ou se os passos de instala\u00e7\u00e3o forem incorrectos, a tens\u00e3o interna da camada de pl\u00e1stico libertar-se-\u00e1. Isto faz com que as t\u00e1buas percam a sua forma. Ver\u00e1 falhas estruturais, como arestas a curvarem-se para cima, centros a levantarem-se ou juntas a partirem-se completamente. Compreender este comportamento f\u00edsico \u00e9 o primeiro passo para salvar o seu pavimento. Quero ajud\u00e1-lo a analisar estas falhas mec\u00e2nicas para que possa proteger o seu investimento.<\/p>\n

\"vis\u00e3o<\/p>\n

Vejamos de perto como estas mudan\u00e7as f\u00edsicas alteram a forma das t\u00e1buas do soalho para que possa identificar o problema exato.<\/p>\n

Quais s\u00e3o os verdadeiros sintomas de um pavimento vin\u00edlico deformado?<\/h2>\n

Um pavimento deformado apresenta tr\u00eas sintomas estruturais distintos com base na fonte de tens\u00e3o.<\/strong><\/p>\n\n\n\n\n\n\n\n
Sintoma<\/th>\nMudan\u00e7a estrutural<\/th>\nFonte principal<\/th>\n<\/tr>\n<\/thead>\n

Digo sempre \u00e0 minha equipa que o diagn\u00f3stico de um pavimento requer a observa\u00e7\u00e3o da forma f\u00edsica da falha. Vamos analisar estas formas espec\u00edficas de danos.<\/p>\n

Como as formas do n\u00facleo se alteram sob tens\u00e3o<\/h3>\n

Quando um pavimento sofre uma forma\u00e7\u00e3o de bolhas, a parte inferior da t\u00e1bua expande-se mais rapidamente do que a parte superior. Isto acontece porque o vapor de \u00e1gua fica retido por baixo. A camada inferior absorve o calor ou a humidade e estica, o que for\u00e7a as extremidades a apontar para cima. O coroamento \u00e9 exatamente o oposto. O centro \u00e9 empurrado para cima porque as extremidades est\u00e3o bloqueadas e n\u00e3o se podem mover.<\/p>\n

Compara\u00e7\u00e3o de falhas estruturais<\/h3>\n\n\n\n\n\n\n\n

Quando as t\u00e1buas se deformam ou rebentam, as juntas de encaixe partem-se porque a for\u00e7a horizontal \u00e9 demasiado elevada. As t\u00e1buas empurram-se umas contra as outras at\u00e9 saltarem do ch\u00e3o. Isto acontece frequentemente porque a sala ficou demasiado quente ou demasiado h\u00famida. Analisei muitas juntas partidas no meu laborat\u00f3rio de f\u00e1brica e a alta press\u00e3o destr\u00f3i sempre o material do n\u00facleo de vinil ao longo do tempo, se n\u00e3o tiver espa\u00e7o para se mover.<\/p>\n

\"tipos<\/p>\n

Agora que j\u00e1 sabe qual \u00e9 o aspeto dos danos no pavimento, vejamos as seis raz\u00f5es espec\u00edficas de fabrico e ambientais que est\u00e3o na sua origem.<\/p>\n

Quais s\u00e3o as 6 principais raz\u00f5es pelas quais o seu pavimento de vinil se deforma?<\/h2>\n

Os pavimentos de vinil deformam-se devido a cinco grandes erros de instala\u00e7\u00e3o e ambientais da HTML.<\/strong><\/p>\n\n\n\n\n\n\n
Categoria<\/th>\nCausas prim\u00e1rias<\/th>\n<\/tr>\n<\/thead>\n
Instala\u00e7\u00e3o<\/td>\nSem folgas de expans\u00e3o, Sem aclimata\u00e7\u00e3o, Prepara\u00e7\u00e3o deficiente do subpavimento<\/td>\n<\/tr>\n
Ambiente<\/td>\nHumidade na base do pavimento, Temperatura extrema, Adesivo errado<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Do ponto de vista do fabrico, o vinil \u00e9 um material termopl\u00e1stico. Isto significa que se expande e contrai naturalmente quando as temperaturas sobem e descem.<\/p>\n

A decomposi\u00e7\u00e3o t\u00e9cnica das 6 causas<\/h3>\n

Se n\u00e3o deixar um espa\u00e7o de dilata\u00e7\u00e3o padr\u00e3o de $1\/4$ polegadas \u00e0 volta do per\u00edmetro, o pavimento em expans\u00e3o bate na parede e deforma-se. A humidade das sub-bases de bet\u00e3o cria uma press\u00e3o hidrost\u00e1tica que for\u00e7a as juntas a deformarem-se. A luz solar direta de grandes janelas cria pontos quentes localizados, o que provoca uma r\u00e1pida expans\u00e3o t\u00e9rmica.<\/p>\n

Uma prepara\u00e7\u00e3o deficiente do subpavimento deixa as depress\u00f5es desiguais que quebram as juntas de encaixe. A utiliza\u00e7\u00e3o de cola de baixa qualidade em \u00e1reas h\u00famidas como as casas de banho faz com que os rebordos se enrolem. Al\u00e9m disso, saltar o per\u00edodo de aclimata\u00e7\u00e3o de 48 horas provoca um choque estrutural \u00e0 medida que o material se ajusta \u00e0 temperatura ambiente. A minha equipa concebe estas camadas para resistir a for\u00e7as normais, mas estes seis erros sobrecarregam a conce\u00e7\u00e3o estrutural das t\u00e1buas.<\/p>\n

\"raz\u00f5es<\/p>\n

Para evitar que estes seis factores destruam a sua bela disposi\u00e7\u00e3o da casa, deve seguir uma rigorosa lista de verifica\u00e7\u00e3o de engenharia antes de come\u00e7ar.<\/p>\n

Como pode evitar que o seu pavimento de vinil se deforme?<\/h2>\n

\u00c9 poss\u00edvel evitar o empeno do vinil combinando controlos ambientais com normas de instala\u00e7\u00e3o precisas.<\/strong><\/p>\n\n\n\n\n\n\n\n

A preven\u00e7\u00e3o \u00e9 muito mais barata do que arranjar uma divis\u00e3o estragada. Nos nossos laborat\u00f3rios de testes de produ\u00e7\u00e3o, verificamos como o vinil se comporta em diferentes configura\u00e7\u00f5es para criar estas regras.<\/p>\n

Normas ambientais e de pr\u00e9-instala\u00e7\u00e3o<\/h3>\n

Deve deixar as t\u00e1buas de vinil repousar na sala de instala\u00e7\u00e3o durante pelo menos 48 horas. O seu sistema HVAC deve funcionar entre $65^{\\circ}\\text{F}$ e $85^{\\circ}\\text{F}$. O subpavimento tem de ser plano num raio de 10 p\u00e9s, num espa\u00e7o de $3\/16$ polegadas, para proteger as juntas de bloqueio.<\/p>\n

Coloque sempre uma barreira de vapor de polietileno de 6 mil\u00edmetros sobre as lajes de bet\u00e3o para bloquear a press\u00e3o hidrost\u00e1tica. Deixe um espa\u00e7o de expans\u00e3o limpo entre $1\/4$ polegadas e $5\/16$ polegadas em cada parede. Nunca prenda um pavimento flutuante colocando arm\u00e1rios de cozinha pesados em cima dele. Utilize cortinas para bloquear os raios solares fortes e manter a humidade interior est\u00e1vel. Estes passos simples protegem a estabilidade dimensional que incorporamos no produto durante o processo de fabrico.<\/p>\n

\"evitar<\/p>\n

Se o seu pavimento j\u00e1 apresenta sinais de danos, n\u00e3o se preocupe ainda, porque algumas situa\u00e7\u00f5es permitem uma repara\u00e7\u00e3o f\u00e1cil.<\/p>\n

O pavimento de vinil deformado pode ser reparado ou salvo?<\/h2>\n

Sim, \u00e9 poss\u00edvel reparar o pavimento vin\u00edlico deformado, dependendo do tipo e da gravidade dos danos estruturais.<\/strong><\/p>\n\n\n\n\n\n\n\n

Como engenheiro, olho para os danos atrav\u00e9s da lente da recupera\u00e7\u00e3o de materiais. Algumas t\u00e1buas podem ser salvas, enquanto outras ficam permanentemente deformadas.<\/p>\n

Tr\u00eas cen\u00e1rios de repara\u00e7\u00e3o para propriet\u00e1rios de casas<\/h3>\n

Se o seu pavimento estiver a empenar porque n\u00e3o existem folgas de expans\u00e3o, tem uma solu\u00e7\u00e3o r\u00e1pida. Pode remover os rodap\u00e9s e aparar as t\u00e1buas do per\u00edmetro com uma multi-ferramenta para criar o espa\u00e7o necess\u00e1rio. Muitas vezes, o pavimento fica novamente plano depois de eliminada a press\u00e3o.<\/p>\n

No caso de danos localizados, pode cortar uma \u00fanica t\u00e1bua de encaixe e colocar uma nova, utilizando um adesivo de pavimento especializado. Mas se os danos graves provocados pela \u00e1gua tiverem quebrado os mecanismos de bloqueio do n\u00facleo interno, chegou a um ponto de n\u00e3o retorno. Tem de substituir todo o sistema. Digo sempre aos meus clientes para verificarem primeiro as juntas de bloqueio antes de comprarem um lote completamente novo de pavimentos.<\/p>\n

\"fixa\u00e7\u00e3o<\/p>\n

Vamos resumir tudo o que discutimos para que possa manter os seus pavimentos perfeitamente lisos durante muitos anos.<\/p>\n

Conclus\u00e3o<\/h2>\n

O empeno do vinil resulta de erros de instala\u00e7\u00e3o e clim\u00e1ticos, mas as folgas de expans\u00e3o adequadas, os testes de humidade e a aclimata\u00e7\u00e3o manter\u00e3o os seus pavimentos planos para sempre.<\/p>\n
