Ho na le mefuta e fapaneng ea li-additives bakeng sa PVC (polyvinyl chloride), tse ka aroloang ka mekhahlelo e latelang ho latela mesebetsi ea tsona, ka metsoako e tloaelehileng le ts'ebeliso e hoketsoeng:
1. Sehatsetsi sa mocheso
Mosebetsi: Ho thibela ho lokolloa ha HCl ka lebaka la ho bola ha mocheso nakong ea ts'ebetso kapa ts'ebeliso ea PVC.
Mefuta e tloaelehileng:
Matswai a loto (a kang trisodium lead sulfate): Theko e tlase empa chefo e phahame, butle-butle e fela.
Khalsiamo e tsitsitseng ea zinki: e sireletsa tikoloho, e sebelisetsoa ho paka lijo le lisebelisoa tsa bongaka.
Metswako ea tin ea tlhaho (joalo ka dibutyltin) e na le ponahalo e ntle 'me e loketse lihlahisoa tsa bongaka.
Rare earth stabilizer: mokhoa o mocha o sireletsang tikoloho.
2. Lisebelisoa tsa polasetiki
Mosebetsi: Eketsa ho tenyetseha le ho fokotsa mocheso oa phetoho ea khalase.
Mefuta e tloaelehileng:
Li-phthalates (tse kang DOP, DBP): Li-Universal, tse nang le chefo e fokolang (tse kang DEHP).
Mekhoa e meng e sireletsang tikoloho: Li-ester tsa citrate (ATBC), oli ea soya e nang le epoxidized (ESO), li-plasticizer tsa polyester.
3. Litlolo
Mosebetsi: Fokotsa khohlano ea machining le ho ntlafatsa phallo ea metsi.
Sehlopha:
Litlolo tse ka hare (tse kang stearic acid): li fokotsa khohlano ea limolek'hule ea PVC.
Litlolo tsa kantle (tse kang parafini): li fokotsa khohlano pakeng tsa PVC le lisebelisoa.
4. Phetoho ea tšusumetso
Mosebetsi: Ntlafatsa khanyetso ea tšusumetso.
Mefuta e tloaelehileng:
CPE (Polyethylene e nang le Chloride): E na le katleho e phahameng.
MBS (methyl methacrylate butadiene styrene copolymer): e loketse dihlahiswa tse bonaletsang.
ACR (acrylic ester): Tshebetso e ntle haholo e felletseng.
5. Lithuso tsa ho sebetsana le ts'ebetso
Mosebetsi: Ntlafatsa matla a ho qhibiliha le ho phalla ha metsi.
Mefuta e tloaelehileng: ACR (joalo ka letoto la Paraloid), EVA (ethylene vinyl acetate copolymer).
6. Lintho tse thibelang malakabe
Mosebetsi: Thibela ho tuka, ho sebediswang thepa ya kaho, dithapo le dikgwele.
Mofuta:
Lisebelisoa tse sa pheleng: aluminium hydroxide, magnesium hydroxide (e mosa tikolohong empa e na le bongata bo boholo ba lintho tse eketsang).
Metswako ya tlhaho: Metswako ya bromine (e kang decabromodiphenyl ether, e lekanyeditsweng hanyane), metswako ya phosphorus (e kang di-ester tsa phosphate).
7. Sesebelisoa sa ho tsitsisa khanya
Mosebetsi: Anti UV botsofali, e sebelisetsoang lihlahisoa tsa kantle.
Mefuta e tloaelehileng:
Li-UV absorbers (tse kang benzotriazoles).
Thibelo ea leseli la amine (HALS)
8. Li-filler
Mosebetsi: Fokotsa litšenyehelo le ho laola ts'ebetso.
Mehlala: Calcium carbonate (calcium e bobebe/calcium e boima), phofo ea talc, le wollastonite.
9. Ditlolo tsa mebala
Mofuta:
Mebala ea tlhaho: e mebala e khanyang.
Mebala e sa tloaelehang: ho hanyetsa boemo ba leholimo hantle.
Bontecn Group China e ikhethile ka ho hlahisa li-additives tsa PVC, Hona joale, k'hamphani e na le basebetsi ba 5 ba phahameng ba R & D, basebetsi ba mahareng ba R & D ba fetang 20, le lihlopha tse fetang 20 tse sebelisanang. Joale k'hamphani le likhoebo tse tsebahalang tsa kantle ho naha ba theha sehlahisoa se secha hammoho, sehlahisoa se ka rarolla mathata a metsoako ea polasetiki ea setso le mathata a litšenyehelo tse phahameng, 'me se fihletse liphetho tse kholo. Ka theknoloji e tsoetseng pele ea ts'ebetso le mekhoa e phethahetseng ea ho lemoha, re tsoela pele ho hlahloba, ho tsepamisa maikutlo lipatlisisong le nts'etsopele, le ho sebelisana le litsi tsa lipatlisiso tsa mahlale selemo ho pota ho nts'etsapele lihlahisoa tse ncha le lits'ebetso tse ncha khafetsa.
