Waa maxay waxyaabaha lagu daro PVC?

Waxaa jira noocyo kala duwan oo lagu daro PVC (polyvinyl chloride), kuwaas oo loo qaybin karo qaybaha soo socda iyadoo lagu saleynayo shaqadooda, iyadoo maaddooyinka gaarka ah iyo isticmaalkooda lagu lifaaqay:

1. Xasilinta kulaylka

Shaqada: Si looga hortago sii deynta HCl sababtoo ah kala-baxa kulaylka inta lagu jiro farsamaynta ama isticmaalka PVC.

Noocyada caadiga ah:

Cusbada rasaasta (sida trisodium lead sulfate): Qiimo jaban laakiin sun badan, si tartiib tartiib ah ayaa loo joojiyaa.

Xasilinta zinc ee kalsiyum: deegaan ahaan u fiican, oo loo isticmaalo baakadaha cuntada iyo aaladaha caafimaadka.

Isku-darka qasacadaha dabiiciga ah (sida dibutyltin) waxay leeyihiin hufnaan wanaagsan waxayna ku habboon yihiin alaabada caafimaadka.

Xasilinta dhulka ee naadirka ah: beddel cusub oo deegaanka u fiican.

2. Balaastikada wax lagu sameeyo

Shaqada: Kordhi dabacsanaanta iyo hoos u dhig heerkulka kala-guurka galaaska.

Noocyada caadiga ah:

Phthalates (sida DOP, DBP): Caalami ah, qayb ahaan xaddidan sunta (sida DEHP).

Beddelaad deegaan ahaan u fiican: Esters-ka Citrate (ATBC), saliidda soybean-ka ee epoxidized (ESO), balaastikada polyester-ka.

3. Saliidaha

Shaqada: Yaree is jiidjiidka mashiinka oo hagaaji dareeraha.

Qaybta:

Saliidaha gudaha (sida stearic acid): waxay yareeyaan isku dhaca u dhexeeya molecular-ka ee PVC.

Saliidaha dibadda (sida paraffin): yaree is jiidjiidka u dhexeeya PVC iyo qalabka.

4. Wax ka beddelka saameynta

Shaqada: Hagaajinta iska caabbinta saameynta.

Noocyada caadiga ah:

CPE (Polyethylene-ka Koloriinta leh): Waxtar sare oo kharash-ool ah.

MBS (methyl methacrylate butadiene styrene copolymer): ku habboon alaabada hufan.

ACR (acrylic ester): Waxqabad dhammaystiran oo aad u fiican.

5. Qalabka wax lagu farsameeyo

Shaqada: Hagaajinta xoogga dhalaalka iyo socodka.

Noocyada caadiga ah: ACR (sida taxanaha Paraloid), EVA (ethylene vinyl acetate copolymer).

6. Waxyaabaha joojiya ololka

Shaqada: Joojinta gubashada, oo loo isticmaalo qalabka dhismaha, fiilooyinka iyo fiilooyinka.

Nooca:

Alaab aan dabiici ahayn: aluminium hydroxide, magnesium hydroxide (deegaan ahaan u fiican laakiin leh tiro badan oo lagu daro).

Isku-dhisyo dabiici ah: Isku-dhisyo Bromine ah (sida decabromodiphenyl ether, qayb ahaan xaddidan), isku-dhisyo fosfooraska ah (sida fosfooraska esters).

7. Xasilinta iftiinka

Shaqada: Ka hortagga gabowga UV, oo loo isticmaalo alaabada bannaanka.

Noocyada caadiga ah:

Nuugayaasha UV (sida benzotriazoles).

Xasiliyaha iftiinka amine ee caqabadda leh (HALS).

8. Buuxiyaasha

Shaqada: Yaree kharashyada oo nidaami waxqabadka.

Tusaalooyin: Kaalshiyam kaarboonayt (kaalshiyam khafiif ah/kaalshiyam culus), budada talc, iyo wollastonite.

9. Midabbo

Nooca:

Midabyo dabiici ah: midab dhalaalaya.

Midabada aan dabiiciga ahayn: iska caabbinta cimilada oo wanaagsan.

Bontecn Group China waxay ku takhasustay soo saarista waxyaabaha lagu daro PVC, Waqtigan xaadirka ah, shirkaddu waxay leedahay 5 shaqaale oo sare oo R & D ah, in ka badan 20 shaqaale oo R & D ah oo dhexdhexaad ah, iyo in ka badan 20 kooxood oo iskaashi ah. Hadda shirkadda iyo shirkadaha ajnabiga ah ee caanka ah waxay si wadajir ah u sameeyaan badeeco cusub, badeecadu waxay xallin kartaa dhibaatooyinka maaddooyinka balaastigga ee dhaqameed iyo dhibaatooyinka qiimaha sare, waxayna gaartay natiijooyin muhiim ah. Iyada oo la adeegsanayo tignoolajiyada habka horumarsan iyo hababka ogaanshaha qumman, waxaan sii wadeynaa sahaminta, diiradda saarista cilmi-baarista iyo horumarinta, iyo iskaashiga machadyada cilmi-baarista sayniska sanadka oo dhan si aan si joogto ah u horumarinno alaabada cusub iyo hababka cusub.
