I-PVC Resin
Kunezinhlobo ezi-4 ze-PVC Resin eziqoqwe ngendlela ye-polymerization
1. Ibanga le-PVC lokumiswa
2. Emulsion Grade PVC
3. I-Bulk Polymerised PVC
4. I-PVC ye-Copolymer
Ibanga lokumiswa PVC
Uhlobo oluvame kakhulu, i-Suspension grade PVC yenziwe ngamaconsi e-polymerizing e-Vinyl Chloride monomer amiswe emanzini.Uma i-Polymerization isiqediwe, i-slurry i-centrifuged futhi ikhekhe le-PVC lomiswa kahle ngamasistimu okushisa akhethekile ukuze kungabi ngaphansi kwe-resin engazinzile ekonakaleni kokushisa.Usayizi wezinhlayiya ze-resin usukela kuma-microns angu-50-250 futhi une-popcorn enezimbobo ezifana nezakhiwo ezimunca kalula ama-Plasticisers.Isakhiwo sezinhlayiya ze-PVC singashintshwa ngokukhetha ama-agent afanele wokumisa kanye ne-Polymerisation Catalyst.Izinhlobo ezinezimbobo ezincane zisetshenziswa kakhulu kuzicelo ze-PVC eziqinile eziqinile noma ezingafakwanga ipulasitiki njengamapayipi e-PVC, iWindows, amaSiding, amaDuctings.Amabanga amisiwe osayizi wezinhlayiyana ezimaholoholo kanye nezakhiwo ezinezimbobo kakhulu zimunca inani elikhulu le-Plasticiser eyenza ingxube eyomile emazingeni okushisa aphansi afinyelela ku-80oC.Izinhlobo ezinezimbotshana eziningi zisetshenziswa ezinhlelweni zePlastiki njengezintambo, Izicathulo, Amashidi Ekhalenda Elithambile kanye Namafilimu njll.
Emulsion Ibanga PVC
I-Emulsion Polymerised PVC iyini i-Paste Grade Resin futhi lokhu cishe kusetshenziselwa ama-Plastisols kuphela.I-resin yebanga lokunamathisela iwusayizi wezinhlayiyana omuhle kakhulu we-PVC okhiqizwa ngokufafaza okomisa i-Emulsion ye-PVC Emanzini ngendlela efana nokukhiqizwa kobisi lwempushana.I-resin yebanga lokunamathisela idinga amandla amaningi ukuze ikhiqize futhi ibiza kakhulu kune-Suspension resin.I-resin yebanga lokunamathisela ithwala amakhemikhali emulsifying kanye nama-catalysts nayo.Ngakho-ke imsulwa kune-Suspension Polymerized or Bulk Polymerized PVC.Ngakho-ke izakhiwo zikagesi ze-Namathisela ama-plastisols e-resin grade zimpofu kakhulu kune-Suspension Resin Compounds.Ukucaca kumpofu kune-Suspension noma i-Bulk PVC.I-resin yebanga lokunamathisela ihlangene ngokwakheka, futhi ayimunceli i-Plasticiser emazingeni okushisa asekamereni.Amazinga okushisa angaphezu kuka-160-180oC ayadingeka ukushayela ipulasitiki ku-resin ngesikhathi sokwelashwa.I-Resin yebanga lokunamathisela isetshenziswa kakhulu ku-Cushion Vinyl Floorings yobubanzi obubanzi.Izendlalelo ezihlukene zokunamathisela ezenziwe ngokukhethekile zimbozwa ku-substrate efanelekile (I-Direct Coating) noma Ephepheni Lokukhipha (Dlulisa i-coating).Izendlalelo zihlanganiswa ngokuqhubekayo kumahhavini amade futhi zigoqwe ngemva kokuba iphepha lokukhulula selisusiwe.Iphansi eligoqiwe lingaba nongqimba oluqinile lwe-semitransparent phezu kwezendlalelo eziphrintiwe nezinamagwebu ezihlezi phezu kwamajazi ayisisekelo agcwele kakhulu ukuze akhe ukujiya.Imiphumela eminingi ekhangayo futhi ecebile ingenzeka futhi lezi zimelela ukuphela okuphezulu kwe-Vinyl Flooring.
I-PVC ene-Bulk Polymerised
I-Bulk Polymerization inikeza uhlobo olumsulwa lwe-PVC resin njengoba kungekho emulsifying noma ejenti yokumisa esetshenziswayo.Zisetshenziswa kakhulu ezinhlelweni ezisobala.Enziwa atholakale ngokuyinhloko kumaqembu yenani eliphansi lika-K, njengoba amaFoil e-PVC Angafakwanga epulasitiki we-Blister Packaging namanye amafilimu Abonisa Ngale Ane-Calender/Extruded Transparent acutshungulwa kangcono kakhulu ukusuka kumabanga Aphansi Enani lika-K.Ukuthuthukiswa kobuchwepheshe be-Suspension resin kukhiphe i-Bulk PVC esikhathini esidlule.
I-Copolymer PVC
I-Vinyl Chloride yenziwe nge-copolymerized nama-comonomers afana ne-Vinyl acetate inikeza uchungechunge lwama-resin anezakhiwo eziyingqayizivele.I-PVAc noma i-Copolymer ye-Vinyl Chloride ne-Vinyl acetate iyona ebaluleke kakhulu.Ukuncibilika okuhle kuzincibilikisi ze-PVAc kuyenza ikhetheke kakhulu kuma-Inks Wokuphrinta weVinyl namasimende ancibilikayo.Kunokusetshenziswa okukhethekile kakhulu kwe-PVAc ekufakweni kwamathayela aphansi futhi iyinhlaka ekhethwayo yamathayili e-Vinyl Asbestos.I-resin empeleni iyisibopho kunesithako esiyinhloko.Nge-Copolymer Resin kungenzeka ukwenza amathayela aphansi ngama-Fillers afana ne-Asbestos kanye ne-Calcium Carbonate accounting efinyelela ku-84% nge-Copolymer nezinye izithasiselo eziyinhlanganisela eziphansi ngo-16%.Amazinga aphezulu kangaka awanakwenzeka nge-Suspension resin njengoba i-viscosity encibilikayo iphakeme kakhulu futhi ayikwazi ukumboza futhi ihlanganise amazinga aphezulu kangaka okugcwalisa okungenayo.Kudingeka izitimela ezikhethekile ezishayela ucingo kumathayela e-asbestos e-Vinyl.Kodwa-ke, ngenxa yokungathandwa kwe-Asbestos, imikhiqizo enjalo iye yaphela kancane kancane.
