PVC K ixabiso 57
PVC K ixabiso 57,
Intlaka yePVC esetyenziselwa ukwenza ibhodi yogwebu,
I-resin ye-PVC enexabiso le-K ye-55-68 ingasetyenziselwa ukuvelisa i-foam enzima, oko kukuthi, imveliso enzima ye-PVC ye-foam ephantsi, eyahluke kwixabiso le-K elinikezelweyo kwingcaciso kunye neencwadi ezidlulileyo.I-PVC resins kunye ne-K yexabiso le-69-77 ibonakaliswe ukuba ifanelekile ukuveliswa kwamagwebu athambileyo.Kukho iindlela ezininzi zokuvelisa i-PVC ye-resin, indlela yokunqunyanyiswa, indlela ye-emulsion kunye ne-polymerization eninzi ye-PVC ye-resin ekhoyo yezinto ezikrwada zeemveliso ezinogwebu, ngokuqhelekileyo ukunqunyanyiswa kunye ne-polymerization eninzi ye-PVC resin ifanelekile.Iipolymers zePVC kunye neepolymers ezihlonyelweyo (iipolymers zegranular) nazo zineprosesa elungileyo kwaye azifane zisetyenziswe ngenxa yexabiso.
I-Polyvinyl Chloride, ebizwa ngokuba yi-PVC, yenye yeendidi zeplastiki eziphuculweyo, imveliso yangoku yesibini kuphela kwi-polyethylene.I-Polyvinyl chloride isetyenziswe ngokubanzi kwishishini, ezolimo kunye nobomi bemihla ngemihla.I-Polyvinyl chloride yikhompawundi yepolymer eyenziwe nge-vinyl chloride.Yi-thermoplastic.Umgubo omhlophe okanye okhanyayo ophuzi.Inyibilika kwiiketoni, ii-esters, i-tetrahydrofurans kunye ne-chlorinated hydrocarbons.Ukuchasana kweekhemikhali okugqwesileyo.Uzinzo olubi lwe-thermal kunye nokumelana nokukhanya, ngaphezu kwe-100 ℃ okanye ukukhanya kwelanga ixesha elide kwaqala ukubola i-hydrogen chloride, ukuveliswa kweplastiki kufuna ukongeza i-stabilizer.Ukufakelwa kombane kulungile, akusayi kutshisa.
IBakala S-700isetyenziselwa ikakhulu ukuvelisa amashiti akhanyayo, kwaye inokuqengqeleka ibe ngamashiti aqinileyo kwaye angaqinanga kwipakethe, imathiriyeli yomgangatho, ifilim eqinileyo yelinen (yephepha lokusonga iilekese okanye ifilimu yokupakisha icuba), njl njl. ifilim enzima, iphepha, okanye ibha enemilo engaqhelekanga yephakheji.Okanye inokutofwa ukwenza amajoyinti, iivalve, iinxalenye zombane, izixhobo zemoto kunye neenqanawa.
