Akpụkpọ anụ PVC (polyvinyl chloride artificial akpụkpọ anụ) bụ ihe dị ka akpụkpọ anụ nke sitere na polyvinyl chloride (PVC) resin, yana mgbakwunye nke ihe mgbakwunye na-arụ ọrụ dị ka plasticizers na stabilizers, site na mkpuchi, calendering, ma ọ bụ lamination. Nke a bụ nyocha zuru oke nke nkọwa ya, nsí ya na usoro mmepụta ya:
I. Nkọwa na Ọdịdị nke PVC Akpụkpọ anụ
1. Ihe mejupụtara
Isi oyi akwa: A kpara akpa ma ọ bụ kpara akpa, na-enye nkwado igwe.
Ngwunye etiti: Ngwunye PVC ụfụfụ nwere ihe ndị na-emepụta ihe na-emepụta ihe na-emepụta ụfụfụ, na-enye ike na ịdị nro.
oyi akwa dị n'elu: Ihe mkpuchi resin PVC, nke enwere ike ịmebe ka ọ mepụta ụdị akpụkpọ anụ ma nwee ike ịnwe ọgwụgwọ abrasion na-eguzogide ọgwụ na mgbochi.
Ụfọdụ ngwaahịa gụnyekwara akwa mkpuchi polyurethane (PU) ma ọ bụ uwe elu na-eguzogide iyi na-enweghị atụ maka arụmarụ ọrụ.
2. Isi njirimara
Njirimara anụ ahụ: Nguzogide hydrolysis, nguzogide abrasion (mgbanwe ruo oge 30,000 ruo 100,000), na nkwụsị ọkụ (ọkwa B1).
Oke arụrụ arụ: iku ume na-adịghị mma (dị ala karịa akpụkpọ anụ PU), ọ na-esiri ike ike na obere okpomọkụ, yana enwere ike ịhapụ plasticizer na iji ogologo oge.
2. Esemokwu toxicity na ụkpụrụ nchekwa nke akpụkpọ anụ PVC
Isi mmalite nke nsị
1. Ihe mgbakwunye na-emerụ ahụ
Plasticizers (plasticizers): phthalates omenala (dị ka DOP) nwere ike ịpụpụ ma gbochie usoro endocrine, karịsịa mgbe ekpughere ya na mmanụ ma ọ bụ gburugburu okpomọkụ.
Ihe na-eme ka ígwè dị arọ: Stabilizers nwere lead na cadmium nwere ike ịkwaga n'ahụ mmadụ, na nchịkọta ogologo oge nwere ike imebi akụrụ na usoro ụjọ.
Vinyl chloride monomer (VCM): VCM fọdụrụnụ na mmepụta bụ carcinogen siri ike.
2. Ihe ize ndụ gburugburu ebe obibi na mkpofu
A na-ahapụ Dioxins na ihe ndị ọzọ na-egbu egbu n'oge a na-akpọ ya ọkụ; ọla ndị dị arọ na-abanye n'ime ala na isi mmiri mgbe a kpochara.
Imegharị ihe siri ike, ọtụtụ n'ime ha na-aghọkwa ndị na-emetọ ihe.
Ụkpụrụ nchekwa yana usoro nchekwa
Ọkọlọtọ amanyere iwu nke China GB 21550-2008 gbochiri ọdịnaya nke ihe dị ize ndụ:
Vinyl chloride monomer: ≤5 mg/kg
Ọkụ na-agbaze: ≤90 mg/kg | Cadmium soluble: ≤75 mg/kg
Mgbanwe ndị ọzọ: ≤20 g/m²
Akpụkpọ anụ PVC na-ezute ọkọlọtọ a (dị ka usoro ndu na cadmium, ma ọ bụ iji mmanụ soybean epoxidized kama DOP) nwere obere ihe ize ndụ nsi. Agbanyeghị, arụmọrụ gburugburu ya ka dị ala karịa ihe ndị ọzọ dị ka akpụkpọ anụ PU na TPU.
Nkwanye Ịzụta: Chọọ maka asambodo gburugburu ebe obibi (dị ka FloorScore na GREENGUARD) ma zere iji okpomọkụ dị elu (> 60°C) na kọntaktị na nri mmanu mmanu.
III. Usoro mmepụta akpụkpọ anụ PVC
Isi Usoro
1. Nkwadebe ihe eji eme ihe
Slurry oyi akwa: PVC resin + plasticizer (dị ka DOP) + stabilizer (nhazi enweghị ndu) + agba.
Ọfụfụ Layer Slurry: Tinye ihe na-afụ ụfụ (dị ka azodicarbonamide) na ihe eji emezigharị (dị ka attapulgite iji kwalite nguzogide ihu igwe).
2. Usoro ịkpụzi
Usoro mkpuchi (Usoro a na-ahụkarị):
Na-ekpuchi akwụkwọ ntọhapụ na akwa oyi akwa nke slurry (ịkpọ nkụ na 170-190 ° C) → Tinye ihe mkpuchi ụfụfụ nke slurry → Laminate na akwa ákwà (polyurethane bonding) → Wepụ akwụkwọ ntọhapụ → Tinye onye na-ahụ maka ọgwụgwọ elu na ihe mkpuchi.
Usoro kalenda:
A na-ewepụta ngwakọta resin site na ịghasa (125-175 ° C) → Edebere ya na kalenda (okpomọkụ rola 165-180 ° C) → Na-ekpo ọkụ na-eji akwa akwa.
Ịfụ ụfụfụ na nhazi nhazi:
Igwe ọkụ na-ekpofu ụfụfụ na-eji njikwa okpomọkụ emebere (110-195 ° C) na ọsọ nke 15-25 m / min iji mepụta usoro microporous.
Embossing (okpukpu ihu abụọ) na ọgwụgwọ UV elu na-eme ka mmetụta tactile na-eyi ma na-eyi nguzogide.
Usoro ọhụrụ omume enyi na gburugburu ebe obibi
Ihe ndị ọzọ: A na-eji mmanụ soybean na polyester plasticizers dochie phthalates.
Mgbanwe na-echekwa ike: Teknụzụ lamination nke nwere akụkụ abụọ na-ebelata oriri ike site na 30%; ndị na-agwọ ọrịa na-edozi mmiri na-edochi mkpuchi nke ihe mgbaze.
- Mgbanwe ọrụ: Tinye ion ọlaọcha (antibacterial), ụrọ gbanwere (na-eme ka ike na ịka nká dịkwuo mma).
IV. Nchịkọta: Ngwa na usoro
Mpaghara ngwa: ime ụgbọ ala (oche), ihe mkpuchi arịa ụlọ, akpụkpọ ụkwụ (elu egwuregwu), akpa, wdg.
Usoro ụlọ ọrụ:
Amụma nchedo gburugburu ebe obibi amachibidoro (dị ka mmachi EU PVC), akpụkpọ anụ TPU/microfiber ji nwayọọ nwayọọ dochie ahịa etiti-na-elu.
A na-emejuputa "Nkọwa nka maka nyocha ngwaahịa Green Design" (T/GMPA 14-2023) na China iji kwalite nkwalite nchebe gburugburu ebe obibi nke ngwaahịa dịka akpụkpọ anụ ala PVC.
Nkwubi okwu: Enwere ike iji akpụkpọ anụ PVC mee ihe n'enweghị nsogbu na nrube isi na ụkpụrụ nchekwa, mana ihe ize ndụ mmetọ na njikọ mmepụta / mkpofu ka dị. Ngwaahịa agbanyere gburugburu gburugburu na-enweghị ọla dị arọ na phthalates ka ahọrọ, a na-akwụkwa nlebara anya na mgbanwe ụlọ ọrụ ahụ gaa na PU/ihe dabere na bio.
