Shira Kalisiyumu Zinc PVC Stabilisateur: PVC nziza, Umusaruro mwiza

Nkibintu byongeweho byongera polyvinyl chloride (PVC),Shira Kalisiyumu Zinc (Ca-Zn) Stabilisateur ya PVCyagaragaye nkuburyo bwatoranijwe kubisanzwe ibyuma biremereye bishingiye kuri stabilisateur (urugero, gurş, kadmium). Ihuza ryihariye ryumutekano, imikorere, no kubahiriza ibidukikije bikemura ibibazo bikenewe murwego rwibicuruzwa byinshi bya PVC. Hano hepfo harambuye birambuye kubyingenzi byingenzi, kwaguka kwagutse, nuburyo bukemura ingingo zimaze igihe zibabaza mubikorwa bya PVC.

1. Ibyiza byingenzi: Umutekano, Imikorere, no kubahiriza?

Shira Ca-ZnPVC Ikomezaihagaze neza kubikorwa byayo byinshi, bituma ibera muri rusange no murwego rwo hejuru-gutunganya PVC.

1.1 Ntabwo ari uburozi & Ibidukikije-Byuzuye

Nta byuma biremereye byangiza (gurş, kadmium, mercure, nibindi), byujuje byuzuye amategeko y’ibidukikije n’umutekano ku isi, harimo Amabwiriza y’ubumwe bw’ibihugu by’Uburayi, Amabwiriza ya RoHS, na CPSIA yo muri Amerika (Itegeko rigenga ibicuruzwa by’umuguzi). Ibi bivanaho ingaruka zubuzima kubakozi bakora n’abakoresha ba nyuma, mu gihe hirindwa ibihano bigenga ibicuruzwa biva mu mahanga byohereza ku masoko mpuzamahanga.

1.2 Gukorera mu mucyo bidasanzwe & Ubwiza bwiza

Bitandukanye na stabilisateur zimwe na zimwe zitera PVC kumuhondo cyangwa igicu, Paste Ca-Zn PVC Stabilizer ikomeza ibintu bisanzwe. Irinda itumanaho ryinshi ndetse no mubicuruzwa bya PVC bifite uruzitiro ruto cyangwa rufite amabara ya PVC, ikintu cyingenzi gisabwa mubisabwa aho abantu babona amashusho (urugero, ibikinisho bibonerana, kuvuza imiti) cyangwa imikorere y'ibicuruzwa (urugero, amacupa asobanutse yo kubona amazi) ni ngombwa.

1.3 Isumbabyose Dynamic Stabilite & Gusaza Kurwanya

PVC ikunda kwangirika k'ubushyuhe mugihe cyo gutunganya (urugero, gukuramo, kalendari) no gusaza kwa okiside mugihe cyo kuyikoresha igihe kirekire. Iyi stabilisateur ikora firime ikingira iminyururu ya PVC, irwanya neza kubora biterwa nubushyuhe (ndetse no ku bushyuhe bwo gutunganya 160-180 ° C) no kugabanya umuvuduko wa UV / okiside. Ibizamini byo murwego byerekana ibicuruzwa byakozwe hamwe nabyo bifite ubuzima bwa 30-50% igihe kirekire ugereranije nabakoresha stabilisateur zisanzwe.

1.4 Gutunganya neza & Impumuro nziza

Hamwe noguhuza neza na resinike ya PVC na plasitike, Paste Ca-Zn PVC Stabilizer ituma ikwirakwizwa rimwe mugihe cyo kuvanga-kugabanya ibibazo byumusaruro nko guhuriza hamwe ibintu cyangwa gushonga kutaringaniye. Iragabanya kandi ibinyabuzima bihindagurika (VOCs) kurekura, bikavamo ibicuruzwa bitagira impumuro nziza. Numukino uhindura umukino ufunzwe-umwanya (urugero, isuku ya firigo) hamwe nimirenge yoroheje (urugero, ibikoresho byubuvuzi).

2. Kwagura ibikorwa byagutse?

Ubwinshi bwayo butuma PasteCa-Zn PVC Ikomezabyiza cyane-gukorera mu mucyo, umutekano-wingenzi, hamwe nimpumuro mbi ya PVC, ikubiyemo urwego rwabaguzi ninganda:

2.1 Ibicuruzwa byinshi-PVC Yoroheje & Semi-Rigid Ibicuruzwa

• Urugo & Gukoresha Buri munsi:Isuku ya firigo isobanutse (irwanya ubushyuhe bukonje no guhuza ibiryo), uturindantoki twa vinyl (ubuvuzi cyangwa ibiryo byo mu rwego rw’ibiribwa, bidafite uburozi), hamwe n ibikinisho bya PVC byoroshye (byujuje ubuziranenge bwa EN 71 na ASTM F963 kubana).

• Inganda ningirakamaro:Amashanyarazi ya PVC asobanutse (kumazi, umwuka, cyangwa kwimura imiti, aho kugaragara kwamazi birinda guhagarara) hamwe nimpapuro za PVC zidakomeye (zikoreshwa mubigaragaza cyangwa gupakira ibikoresho bya elegitoroniki).

2.2 Ibicuruzwa-byo mu rwego rwa PVC Ibicuruzwa (Byinshi-Bisanzwe, Impumuro mbi)

Ubuvuzi PVC busaba gukurikiza byimazeyo biocompatibilité na sterility. Iyi stabilisateur yujuje ISO 10993 (isuzuma ryibinyabuzima ryibikoresho byubuvuzi) hamwe na USP yo mu cyiciro cya VI, bigatuma ibera:

• Imfashanyo z'ubuhumekero:Masike ya Oxygene hamwe nigituba cya nebulizer (impumuro nke itanga ihumure ryumurwayi mugihe cyo kuyikoresha igihe kirekire).

• Gucunga amazi:Imiyoboro y'amaraso (IV) itonyanga, imifuka yamaraso (irwanya imiti ikoreshwa namaraso cyangwa imiti), na catheters.

• Ibikoresho byo gutera inshinge:Ibikoresho bya siringe hamwe nibikoresho byo gutera inshinge (bidafite uburozi, kwemeza ko hatabaho ibintu byangiza mumazi yumubiri).

2.3 Ibiribwa-Twandikire Ibicuruzwa bya PVC

Usibye gukoresha ubuvuzi, hemejwe kandi gusaba-guhuza ibiryo (urugero, firime ya PVC ibonerana yo gupakira ibiryo, imikandara ya convoyeur mu nganda zitunganya ibiryo), kuko yubahiriza FDA 21 CFR Igice cya 177.1520 (PVC isubizaho ibiryo).

3. Gukemura Ingingo Zingenzi Zububabare Mubikorwa bya PVC

Abakora PVC bakunze guhura nibibazo bijyanye numutekano, imikorere, no kubahiriza - ibibazo Paste Ca-Zn PVC Stabilizer ikemura neza:

3.1 Kurandura ingaruka zikomeye zanduye

Imiyoboro gakondo ishingiye ku mashanyarazi itera ibyago byo guhura n'abakozi (binyuze mu mukungugu cyangwa umwotsi) no kwanduza ibicuruzwa byanyuma (urugero, kuruka biva mu bikinisho cyangwa gupakira ibiryo). Iyi stabilisateur iremereye idafite ibyuma ikuraho ibyo byago, irinda kwibutsa ibicuruzwa no kurinda izina ryiza.

3.2 Gutsinda igihombo cyo gukorera mu mucyo

Stabilisateur nyinshi zifata plastike ya PVC cyangwa resin, bigatera ibara cyangwa ibicu. Shira Ca-Zn PVC Stabilisateur ya reaction nkeya irinda ibintu neza, igabanya igipimo cyibicuruzwa ku bicuruzwa bikorera mu mucyo (urugero, ibice 10-15% bike bifite inenge mu bikinisho cyangwa mu kuvura imiti).

3.3 Kwirinda Iyangirika ryubushyuhe mugihe cyo gutunganya ubushyuhe bwinshi

PVC ibora ku bushyuhe bwinshi, irekura aside hydrochloric (HCl) kandi igatera ibara ryibintu cyangwa ubukana. Iyi stabilisateur irwanya ubushyuhe bukomeye ituma PVC itajegajega mugihe cyo kuyisohora cyangwa kuyibumba, bigatuma ubuziranenge bwibicuruzwa bigabanuka kandi bikagabanya igihe cyo kwangirika kw ibikoresho (biterwa na HCl).

3.4 Guhura Impumuro & Biocompatibilité Ibisabwa ku Mirenge Yumva

Ibicuruzwa byubuvuzi ningo murugo PVC akenshi binanirwa ibyemezo kubera impumuro zisigaye cyangwa ubumara bwangiza. Iyi stabilisateur nkeya ya VOC ihumanya hamwe nibidafite uburozi byemeza kubahiriza ibizamini bya biocompatibilité yubuvuzi hamwe n’ibipimo by’impumuro yo mu rugo, byihutisha isoko-ku bicuruzwa bishya.

Shira Kalisiyumu Zinc PVC Stabilizer ikuraho itandukaniro riri hagati yumutekano, imikorere, no kubahirizaAbakora PVC. Umwirondoro wacyo udafite uburozi, wangiza ibidukikije wujuje amabwiriza y’isi yose, mu gihe gukorera mu mucyo, gutekana, no gutunganya ibintu byongera ubuziranenge bw’ibicuruzwa mu nzego z’abaguzi, inganda, n’ubuvuzi. Mugukemura ibibazo byibanze nko kwanduza ibyuma biremereye, gutakaza umucyo, no kwangirika kwubushyuhe, byahindutse inyongera yingirakamaro kubikorwa bya PVC bifite agaciro kanini-cyane cyane bisaba umutekano muke cyangwa amahame yuburanga.
