I-Polyvinyl Chloride (PVC)
I-Polyvinyl Chloride (i-PVC) i-polymer ye-thermoplastic yezoqoqosho kunye ne-versatile esetyenziswa ngokubanzi kwishishini lokwakha kunye nelokwakha ukuvelisa iiprofayili zeminyango kunye nefestile, imibhobho (ukusela kunye namanzi amdaka), i-wire kunye ne-cable insulation, izixhobo zonyango, njl.
Yimathiriyeli yesithathu ngobukhulu be-thermoplastic ngomthamo emva kwe-polyethylene kunye ne-polypropylene.
I-PVC isetyenziswa ngokubanzi kuluhlu olubanzi lwemveliso, ubugcisa kunye nezicelo zemihla ngemihla kubandakanya ukusetyenziswa ngokubanzi kwizakhiwo, ezothutho, ukupakishwa, umbane / umbane kunye nezicelo zempilo.
Kwi-polymerization yokumiswa kwe-vinyl chloride, inkqubo ehlakaziweyo inefuthe elithe ngqo kwimveliso, i-PVC resin, kunye nomgangatho wokwenziwa kwayo kunye neemveliso.I-Hydroxypropyl MethylCellulose inceda ekuphuculeni ukuzinza kwe-thermal ye-resin kunye nokulawula ukusabalalisa ubungakanani be-particle (ngamanye amazwi, ukulungelelanisa ubuninzi be-PVC), kunye ne-akhawunti ye-0.025% -0.03% yemveliso ye-PVC.I-resin ye-PVC eyenziwe kumgangatho ophezulu we-Hydroxypropyl MethylCellulose ayinakuqinisekisa kuphela umgca wokusebenza kunye nemigangatho yamazwe ngamazwe, kodwa ingaba neepropati ezibonakalayo ezibonakalayo ezibonakalayo, iipropati ezibalaseleyo zamasuntswana kunye nokuziphatha okugqwesileyo okunyibilikayo kwerheological.
I-PVC yinto ehlala ixesha elide kwaye ihlala ixesha elide enokuthi isetyenziswe kwizicelo ezahlukeneyo, nokuba ziqinile okanye zibhetyebhetye, zimhlophe okanye zimnyama kunye noluhlu olubanzi lwemibala phakathi.
Kwimveliso ye-synthetic resins, njenge-polyvinyl chloride (PVC), i-polyvinylidene chloride, kunye nezinye ii-copolymers, i-polymerization yokumiswa yeyona nto isetyenziswa ngokuqhelekileyo kwaye kufuneka ibe yi-hydrophobic monomers engaguqukiyo enqunyanyiswe emanzini.Njengeepolymers ezinyibilikayo emanzini, imveliso ye-Hydroxypropyl MethylCellulose inomsebenzi ogqwesileyo womphezulu kunye nemisebenzi njenge-colloidal agents ezikhuselayo.IHydroxypropyl MethylCellulose inokuthintela ngokufanelekileyo amasuntswana epolymeric ekuveliseni kunye ne-agglomeration.Ngaphaya koko, nangona iHydroxypropyl MethylCellulose iyipolymer enyibilikayo emanzini, inokunyibilika kancinci kwiimonomers ze-hydrophobic kwaye inokonyusa i-monomer porosity yokuveliswa kwamasuntswana epolymeric.
Iimveliso ze-Anxin HPMC zinokuphucuka ngezi propati zilandelayo kwi-PVC:
·ezona arhente zixhaphakileyo zokuxhoma.
·Ukulawula ubungakanani bamasuntswana kunye nokuhanjiswa kwawo
·Unefuthe kwi-porosity
·Ichaza ubunzima bePVC.
