Yini abaqinisi be-PVC

Abaqinisi be-PVCziyizithasiselo ezisetshenziselwa ukuthuthukisa ukuqina okushisayo kwe-polyvinyl chloride (PVC) nama-copolymers awo. Kumapulasitiki we-PVC, uma izinga lokushisa elisebenza lidlula ama-160 ℃, ukubola okushisayo kuzovela futhi i-hcl gesi izokhiqizwa. Uma kungacindezelwa, lokhu kuvulwa okushisayo kuzothuthuka ngokwengeziwe, kuthonye ukuthuthukiswa kanye nokusetshenziswa kwamapulasitiki we-PVC.

Ucwaningo luthole ukuthi uma amapulasithi e-PVC aqukethe amanani amancane okuhola usawoti, i-metal insipho yensimbi, i-phenol, amomatic amine, nokunye ukungcola, ukuwohloka kwawo kungahle kuncishiswe ngezinga elithile. Lezi zifundo zikhuthaza ukusungulwa kanye nokuthuthukiswa okuqhubekayo kwe-PVC Stailivilizer.

Abaqinisi be-PVC abajwayelekile bafaka ama-orgatin anatiliviliving, abagcina usawoti wensimbi, kanye nama-inorganic usawoti ogcina. Abaqinisi be-Organin basetshenziswa kabanzi ekukhiqizweni kwemikhiqizo ye-PVC ngenxa yokubonakala kwabo, ukumelana kahle kwesimo sezulu, kanye nokuhambisana. Ama-Metal Salt Startilizer ajwayele ukusebenzisa i-calcium, i-zinc, noma usawoti we-barium, onganikeza ngokuqina okungcono okushisayo. Ama-inorganic usawoti okugcina kasawoti onjenge-tribasic ehola i-sulfate, i-dibasic lead phosphite, njll. Yiba nokuwohloka kwesikhathi eside nokufakelwa kukagesi okuhle. Lapho ukhetha i-PVC Stabilizer, kufanele ucabangele izimo zohlelo lokusebenza zemikhiqizo ye-PVC kanye nezakhiwo ezidingekayo. Abaqiniswa abahlukahlukene bazothinta ukusebenza kwemikhiqizo ye-PVC ngokomzimba nangokwekhemikhali, ukwakheka okuqinile nokuhlola okuqinile kuyadingeka ukuqinisekisa ukufaneleka kwabakhuthazi. Ukwethulwa okuningiliziwe kanye nokuqhathaniswa kwama-PVC ahlukahlukene okuqinisa okulandelayo:

I-Organin Stabilizer:Abaqinisi be-Organin bayizitebhisi ezisebenza kahle kakhulu zemikhiqizo ye-PVC. Amakhompiyutha abo yimikhiqizo yokuphendula ye-Organin oxides noma i-organin chlorides enama-acid afanele noma ama-esters.

Abaqinisi be-Organin bahlukaniswe ngesibabule-esiba ne-sulfur-free. Ukuqina kwe-Sulfur-equkethe izitebele kuvelele, kepha kunezinkinga ekunambithekeni nasekunqandeni okufana nezinye izivumelwano eziqukethe ama-sulfur. Abaqinisi be-On-Sulfur Organilin bavame ukususelwa ku-solec acid noma isigamu se-solec acid ester. Bathanda ama-methyl tin stivilizer abambelela kangako ukushisa okuthe xaxa ngokuqina okungcono kokuzinza.

Abaqinisi be-Organin ikakhulukazi basetshenziswa ngokufakwa kokudla kanye neminye imikhiqizo ye-PVC esobala efana ne-hoses esobala.

Ukuhola izitebele:Abaqinisi abajwayelekile bokuhola bafaka phakathi amakhompiyutha alandelayo: I-Dibasic Lead Stearate, i-Hydrasic Holy Sulfate, i-Dibasic lead phthalate, kanye ne-dibasic lead phosphate.

Njengoba ukuqina kokushisa, amakhompiyutha okuhola ngeke kulimaze izakhiwo zikagesi ezinhle kakhulu, ukumuncwa kwamanzi okuphansi, kanye nokuphikiswa kwesimo sezulu kwangaphandle kwezinto zokwenziwa kwe-PVC. Noma kunjalo,Hola ukuqinayiba nezingqinamba ezinjengokuthi:

- Ukuba nobuthi;

- Ukungcoliswa kokuwela, ikakhulukazi ngesibabulfur;

- Kwenziwa ukuhola i-chloride, ezokwakha imichilo emikhiqizweni eqediwe;

- Isilinganiso esindayo, okuholele ekutheni kungagculisi isisindo / isilinganiso sevolumu.

- Abaqinisi ukuhola bavame ukwenza imikhiqizo ye-PVC Opaque ngokushesha futhi ihlukanise ngokushesha ngemuva kokushisa okuqhubekayo.

Naphezu kwalezi zinto ezinzima, abaqinisi ukuhola basamukelwa kabanzi. Ngokufakelwa kukagesi, abaqinisi abahamba phambili bayakhethwa. Ukuzuza emphumeleni wayo ojwayelekile, imikhiqizo eminingi eguquguqukayo futhi eqinile ye-PVC yatholakala njengezingqimba zangaphandle zekhebula, amabhodi aqinile we-Opaque PVC, amapayipi anzima, izimpaphe zokufakelwa.

Ama-Metal Salt Startilizer: Abahlanganisiwe usawoti wensimbizihlanganisa amakhompiyutha ahlukahlukene, okuvame ukuklanywa ngokuya ngezinhlelo zokusebenza ezithile ze-PVC nabasebenzisi. Lolu hlobo lwe-Stabilizelizer luvele kusuka ekungeneni kwe-barium Succeine kanye ne-Cadmium Palm Acid kuphela ekuhlanganiseni ngokomzimba kwe-barium insipho, i-organizes, ama-phosphite, ama-phososite, ama-viscosity, ama-ejenti we-UV, ama-lubtosity, kanye nokunambitheka. Ngenxa yalokhu, kunezici eziningi ezingathinta umphumela we-Stabilizer Final.

Abaqinisi bensimbi, njenge-barium, i-calcium, kanye ne-magnesium abavikeli umbala wokuqala wezinto zokwenziwa kwe-PVC kepha banganikeza ukumelana nokushisa kwesikhathi eside. Izinto ze-PVC zizinzile ngale ndlela ziqala ophuzi / i-orange, kancane kancane ziphenduka zinsundu, futhi ekugcineni zibe mnyama ngemuva kokushisa njalo.

I-Cadmium ne-Zinc Stagilivilivilivilivilivilizer basetshenziswa okokuqala ngoba basobala futhi bangagcina umbala wokuqala wemikhiqizo ye-PVC. Ukulondolozwa kwesikhathi eside okuhlinzekwe yi-cadmium kanye ne-zinc ukuqina kubi kakhulu kunalokho okuhlinzekwa yi-barium, okuvame ukungcolisa ngokuzumayo ngesibonakaliso esincane noma esingenalo.

Ngaphezu kwesici se-Metal Ratio, umphumela we-Metal Salt Startilivilizers uhlobene nezinqubo zazo zikasawoti, okuyizinto eziphambili ezithinta izakhiwo ezilandelayo: ukugcoba, ukuhamba, ukuvela obala, ukuguquguquka kombala we-PVC, kanye nokuqina kombala we-PVC, kanye nokuqina okushisayo kwe-PVC. Ngezansi kubangezelwa yizinsimbi eziningana zensimbi ezihlanganisiwe: 2-ethylopaate, phenolate, benzoate, futhi turate.

Ama-Metal Salt SALTILIHIADER asetshenziswa kabanzi emikhiqizweni ethambile ye-PVC nemikhiqizo ebonakalayo ye-PVC ye-PVC efana nokupakishwa kokudla, okudliwayo kwezokwelashwa, nokupakishwa kwemithi.
