PVC Stabilisateur mu musaruro wimpu zubukorikori: Gukemura umutwe munini wabakora

Uruhu rwubukorikori (cyangwa uruhu rwubukorikori) rwabaye ingenzi mu nganda kuva kumyambarire kugeza kumodoka, bitewe nigihe kirekire, ihendutse, kandi ihindagurika. Kubakora uruhu rwa PVC rushingiye ku ruhu, icyakora, igice kimwe gihagarara hagati yumusaruro woroshye no kubabara umutwe bihenze:PVC stabilisateur. Izi nyongeramusaruro ningirakamaro mukurinda kwangirika kwa PVC mugihe cyo gutunganya ubushyuhe bwinshi (nka kalendari cyangwa gutwikira), ariko guhitamo stabilisateur itari yo - cyangwa gucunga nabi imikoreshereze yayo - bishobora gutera kunanirwa kwiza, ihazabu yubuyobozi, hamwe ninyungu yatakaye.

Reka dusenye ingingo zo hejuru zibabaza PVC abakora uruhu rwimpu bahura na stabilisateur, nibisubizo bifatika byo kubikemura.

Ububabare Ingingo ya 1: Ubushyuhe bukabije bwubushyuhe = Ibikoresho byasesaguwe & Kwanga

Kwiheba cyane? PVC yangirika byoroshye iyo yashyutswe hejuru ya 160 ° C - neza nubushyuhe bwakoreshejwe muguhuza ibisigazwa bya PVC hamwe na plasitike hanyuma bigakora uruhu rwubukorikori. Hatabayeho guhagarara neza, ibintu bihinduka umuhondo, bigatera ibice, cyangwa bisohora imyotsi yubumara (nka aside hydrochloric). Ibi biganisha kuri:

• Igipimo kinini cyo gusakara (kugeza 15% mu nganda zimwe).

• Amafaranga yo gukora kubice bitagira inenge.

• Gutinda kubahiriza ibicuruzwa byabakiriya.

Gakondo imwe igizwe na stabilisateur (urugero, imyunyu ngugu y'ibanze) akenshi igabanuka mugihe kirekire. Ahubwo, hitamocalcium-zinc (Ca-Zn) igizwe na stabilisateurcyangwa ibinyabuzima bya organotine - byombi bigenewe PVC uruhu rwihariye rukenewe gutunganya:

• Uruvange rwa Ca-Zn rutanga ubushyuhe buhebuje bwumuriro (uhanganye na 180-200 ° C muminota 30+) kandi urahuza nibyoroshya bikoreshwa muruhu rworoshye.

• Stabilisateur ya Organotine (urugero, methyltin) itanga umucyo mwinshi no kugumana amabara-byiza cyane kuruhu rwohejuru rwohejuru (urugero, imyambarire ya vegan, upholster).

• Impanuro: Impinduka zombi hamwe ninyongeramusaruro nka antioxydants cyangwa imashini ya UV kugirango yongere ubushyuhe bwumuriro.

Ububabare Ingingo 2: Ibidukikije & Kugenzura Kutubahiriza

?

Amabwiriza y’isi yose (EU REACH, US CPSC, Uburinganire bw’Ubushinwa) arahagurukira kurwanya stabilisateur zifite ubumara - cyane cyane isasu, kadmium, n’uburyo bushingiye kuri mercure. Ababikora benshi baracyashingira kumunyu uhendutse, gusa kugirango bahure:

• Kuzana ibicuruzwa kubicuruzwa byarangiye.

• Amande menshi kubera kutubahiriza.

• Kwangiza izina ryikirango (abaguzi basaba uruhu rwicyatsi "icyatsi").

Igisubizo: Emera Ibidukikije-Byiza, bigenga-byubahiriza umutekano

Gutobora uburozi bwubumara buremereye kubusa, butarimo kadmium bwujuje ubuziranenge bwisi:

• Ca-Zn stabilisateur: Yujuje byuzuye na REACH na RoHS, bituma iba nziza kubakora ibicuruzwa byibanda hanze.

• Ntibisanzwe isi ihindagurika: Uburyo bushya buhuza ubushyuhe bwumuriro nuburozi buke-bukomeye kubidukikije byanditseho uruhu rwimpu.

• Kugenzura urunigi rwawe: Korana nabatanga stabilisateur batanga ibyemezo byabandi bantu (urugero, SGS, Intertek) kugirango wirinde uburozi bwihishe.

Ububabare Ingingo ya 3: Ubworoherane budahuye & Kuramba

?

Uruhu rwakozwe nubuhanga rushingiye kumiterere yubukorikori - birakomeye, kandi birananirana; byoroshye cyane, kandi irira inkweto. Stabilisateur igira ingaruka itaziguye: amahitamo make arashobora gukora hamwe na plasitike, kugabanya guhinduka cyangwa gutuma ibintu bikomera mugihe runaka.

Igisubizo: Abadozi badoda kugirango barangize-Gukoresha Ibisabwa

Uruhu rwubukorikori ntirumeze kimwe - bityo stabilisateur yawe nayo ntigomba kuba. Hindura formulaire yawe ukurikije ibicuruzwa:

• Kubikorwa byoroshye (urugero, gants, imifuka): Koreshaamazi ya Ca-Zn, ivanga neza na plasitike kugirango ikomeze guhinduka.

• Kubikoresha imirimo iremereye (urugero, imyanya yimodoka, imikandara yinganda): Ongerahobarium-zinc (Ba-Zn) stabilisateurhamwe na epoxisize amavuta ya soya (ESBO) kugirango yongere amarira.

• Banza ugerageze uduce duto: Koresha ibigeragezo hamwe nubushakashatsi butandukanye (mubisanzwe 1-3% byuburemere bwa PVC) kugirango ubone ahantu heza hagati yubworoherane no gutuza.

Ububabare Ingingo ya 4: Kuzamuka kw'ibiciro bya Stabilisateur Ibikoresho bito

?

Muri 2024–2025, ibiciro byibikoresho byingenzi bya stabilisateur (urugero, okiside ya zinc, amabati kama) byazamutse kubera ikibazo cyo kubura amasoko. Ibi bikuraho inyungu zingana kubakora ibicuruzwa bito bito bito.

Igisubizo: Hindura Dosage & Shakisha Ibivanze Byakoreshejwe

• Koresha “igipimo cyiza ntarengwa”: Gukoresha stabilisateur isesagura amafaranga udatezimbere imikorere. Korana nabatekinisiye ba laboratoire kugirango ugerageze ijanisha ryo hasi cyane (akenshi 0.8-2%) ryujuje ubuziranenge.

• Kuvanga stabilisateur yongeye gukoreshwa: Ku mpu zidasanzwe zidasanzwe (urugero, gupakira, inkweto zihenze), vanga 20-30% ya stabilisateur ya Ca-Zn itunganyirizwa hamwe n’isugi - ibi bigabanya ibiciro 10-15% utitaye ku gutuza.

• Funga mumasezerano maremare yabatanga: Ganira ibiciro byagenwe nabakora inganda zizewe kugirango wirinde ihindagurika ryibiciro.

Stabilisateur = Ubuzima Buzima

Kubakora PVC yububiko bwimpu, guhitamo stabilisateur ikwiye ntabwo ari ugutekereza gusa - nicyemezo cyibikorwa bigira ingaruka nziza, kubahiriza, no kunguka. Mugucamo ibintu bishaje, uburozi kubintu byiza cyane, bitangiza ibidukikije, hamwe nubudozi bwo kurangiza gukoresha, urashobora kugabanya imyanda, kwirinda ingaruka zogutegekwa, no gutanga ibicuruzwa bigaragara kumasoko arushanwa.

Witeguye kuzamura ingamba zawe? Tangira ukoresheje ikizamini cya Ca-Zn cyangwa organotine igizwe - ibisakuzo byawe (n'umurongo wo hasi) bizagushimira.
