I-Polyvinyl Chloride yeMveliso yoShishino

I-Polyvinyl chloride (PVC), eyaziwa njenge-PVC, i-polymer eguquguqukayo esetyenziswa kwiindidi ezahlukeneyo zamashishini.Iveliswa ngepolymerizing vinyl chloride monomer (VCM) ngokusebenzisa i-free-radical polymerization mechanism ngoncedo lweeperoxides, i-azo compounds okanye ezinye iziqalisi, kunye nokukhanya kunye nobushushu.I-PVC ibandakanya i-vinyl chloride homopolymers kunye ne-vinyl chloride copolymers, ngokudibeneyo ebizwa ngokuba yi-vinyl chloride resins.Ngeempawu zayo ezibalaseleyo kunye nokuguquguquka, iPVC iye yaba yinto ekhethwayo kwizicelo ezininzi.

Ukusetyenziswa

Kwishishini lokwakha, iPVC ixabiswa ngenxa yokuqina kunye nokuguquguquka kwayo, iyenza ibe yinto efanelekileyo yokwakha.Isetyenziswa ngokuqhelekileyo kwiinkqubo zombhobho ngenxa yokumelana nokubola kunye neempawu ezibalaseleyo zokuhamba.Ukongezelela, isetyenziswe ngokubanzi kwimveliso yesikhumba somgangatho kunye neetayile zomgangatho, ukubonelela ngesisombululo esinamandla, esinoqoqosho kunye nokulula ukugcina umgangatho.Ukuguquguquka kwePVC akukhawulelwanga kulwakhiwo, njengoko kukwasetyenziselwa ukwenza iimveliso zoshishino ezifana neengcingo, iintambo kunye neefilimu zokupakisha.Iimpawu zayo zokugquma umbane, ukubuyiswa komlilo kunye nokwakheka kwenza kube yinto ebalulekileyo kule miba.

Ukubaluleka kwePVC kunabela kubomi bethu bemihla ngemihla njengoko isetyenziswa kwizinto ezahlukeneyo zemihla ngemihla.Iimveliso zesikhumba ze-Faux ezifana neengxowa, izicathulo kunye ne-upholstery zihlala zixhomekeke kwi-PVC ngenxa yeendleko zayo, ukuguquguquka koyilo kunye nokulula kokucoca.Ukusuka kwiibhegi ezinesitayile ukuya kwiisofa ezitofotofo, i-PVC yesikhumba yefaux ibonelela ngenye indlela enomtsalane nesebenzayo.Ukongeza, i-PVC ikwasetyenziselwa ukupakisha iifilimu ukugcina ubutsha kunye nomgangatho wokutya kunye neemveliso zabathengi.Ukukwazi ukuchasana nokufuma kunye nezinto zangaphandle kwenza kube yinto efanelekileyo kakhulu yokupakisha.

Ukuqukumbela, i-PVC yinto ethembekileyo kwaye eguquguqukayo enokuthi isetyenziswe kuluhlu olubanzi lwamashishini kunye nokusetyenziswa.Nokuba kulwakhiwo, ukuveliswa kwemizi-mveliso okanye iimveliso zemihla ngemihla, indibaniselwano eyodwa yePVC yeempawu ezibandakanya ukuqina, ukuguquguquka kunye nokusebenza kakuhle kweendleko kuyenza ibe yinto yokuzikhethela.Ukuguquguquka kwayo kunye nokubaluleka kwayo kugxininiswe kwiinkalo ezininzi zesicelo ezifana nezixhobo zokwakha, iimveliso zoshishino, isikhumba somgangatho, iithayile zomgangatho, isikhumba sokwenziwa, imibhobho, iingcingo kunye neentambo, iifilimu zokupakisha, njl njl. kumashishini kunye nabathengi.
