Anhydride nziza ya Phthalic (PA): Ishingiro ry'inyubako ku miti ikoreshwa cyane ya polymers na shimi

Amashami y'ingenzi yo gusaba

1. Polyester Resins na Thermoplastics: Ishingiro rya Polymers zo mu nganda
Anhydride ya Phthalic ikoreshwa cyane cyane mu gukora resins za polyester zidafite ubushyuhe (UPRs), igice cy'ingenzi muri pulasitiki zishyigikiwe na fiberglass (FRPs):
Porogaramu za FRP:
Mu nganda zikora imodoka (urugero, inganda zikora imodoka zo mu Burayi), UPR zikomoka kuri PA zikoreshwa mu gukora ibice byoroheje by'umubiri, amabampa, n'ibice biri munsi y'ikoti, bigabanya uburemere bw'imodoka kandi bikongera uburyo bwo gukoresha lisansi neza.
Mu ngufu zikomoka ku muyaga, resine zishingiye kuri PA ni ingenzi mu gukora ibyuma bya turbine z'umuyaga, bitanga imbaraga nyinshi no kuramba kugira ngo bihangane n'ikirere kibi cyane mu mirima yo mu nyanja (urugero, imishinga yo mu Nyanja y'Amajyaruguru).
Inyongeramusaruro za Thermoplastic:
Ikora nk'ikintu gihindura umusaruro wa polyvinyl chloride (PVC), yongera ubushobozi bwo koroshya no gutunganya. Urugero, mu nganda zo muri Aziya zikora imiyoboro ya PVC, pulasitiki zikoresha PA zinoza ubushobozi bwo kurwanya imiyoboro ku miyoboro y'amazi n'imyanda.

2. Amarangi, Irangi, n'Ibyuma bikonjesha: Imikorere n'Iramba
Alkyd Resins:
PA ni ikintu cy'ingenzi mu mavuta ya alkyd resins, akoreshwa mu marangi y’ubwubatsi (urugero, amarangi yo hanze y’inzu muri Amerika ya Ruguru) kubera ko arwanya ikirere neza kandi agatuma amabara agumana neza. Amarangi ashingiye kuri alkyd kandi arinda ubuso bw’ibyuma mu nganda (urugero, ibiraro, imashini) kwangirika.
Imyambaro ya Epoxy:
Mu gusiga irangi rivanze, ibikomoka kuri PA byongera uburyo bwo gufatana no kudakoresha imiti ya epoxy, bikaba ari ingenzi cyane mu gusakara mu byumba byo gusukura imiti no mu nganda zitunganya ibiribwa.
Ibikoresho byo gukodesha:
Ikoreshwa muri 热熔胶 (kole ishyushye ishongesha) mu gupakira no gufatanya ibitabo, PA yongera imbaraga zo gushonga no gufatanya, bigatuma habaho imikorere yizewe mu nganda zikora vuba cyane (urugero, inganda zo mu Burayi zipakira).

3. Imashini zikora pulasitiki n'imiti yihariye: Kongera imiterere y'ibikoresho
Ibyuma bikoresha pulasitiki bya Phthalate:
PA ni yo ntandaro yo gukora diisononyl phthalate (DINP) na diethyl phthalate (DEP), bikoreshwa cyane mu bikoresho bya PVC nk'ibikinisho, ibikoresho byo mu nzu, n'ibikoresho by'ubuvuzi. Ibi bikoresho byo mu bwoko bwa pulasitiki byongera ubushobozi bwo koroshya ibintu mu gihe bikomeza kubahiriza amabwiriza ya EU REACH yo kugabanya uburozi (urugero, mu bicuruzwa by'abana).
Impuzandengo z'imiti:
Mu gukora imiti, ibikomoka kuri PA bikoreshwa mu gukora imiti nk'imiti irwanya ubushyuhe n'imiti irwanya indwara. Urugero, igira uruhare mu gukora imiti irwanya indwara ya cephalosporin, ikaba ari ingenzi cyane mu kuvura indwara zandura ku isi hose.

4. Ubuhinzi no kurwanya udukoko: Ibisubizo birambye
Imiti yica udukoko n'imiti irwanya udukoko:
Imiti ikomoka kuri PA ikoreshwa mu gukora ibikomoka ku buhinzi, nka pyrethroids zikozwe mu buryo bwa synthetic mu kurwanya udukoko. Mu mirima ya soya yo muri Amerika y'Epfo, iyi miti ifasha mu kurinda imyaka udukoko twibasira ibidukikije mu gihe bigabanya ingaruka mbi ku bidukikije.
Polymers zishobora kubora:
Nk’ikintu kibongera ibidukikije mu bikoresho bya pulasitiki bishobora kubora, PA igira uruhare mu iterambere ry’ibikoresho byo gupfunyikamo bitangiza ibidukikije (urugero, ibikoresho by’ibiribwa bikomoka ku bimera) bigabanya kwishingikiriza ku bikomoka kuri peteroli.

5. Serivisi zo muri Laboratwari n'ubushakashatsi
Gukora ikorwa ry’ibinyabuzima:
PA ni reagent ikoreshwa mu buryo butandukanye mu ma laboratwari y’ubushakashatsi n’inganda mu kuvura ingaruka nka Friedel-Crafts acylation, ikoreshwa mu gukora aromatike na amarangi ahumura. Ifasha kandi gukora phthalimide, urwego rw’ingenzi mu bushakashatsi mu by’imiti no mu buhinzi.
Ubumenyi bwa polima:
Ikoreshwa muri laboratwari za polymer mu kwiga isano iri hagati y’imiterere n’imiterere ya polyester, bigatuma habaho iterambere ry’ibikoresho bigezweho byo mu kirere n’ibikoresho by’ikoranabuhanga (urugero, irangi ririnda ubushyuhe ku byuma bya satelite).

Ibisobanuro

Urupapuro rwo kugenzura ubuziranenge

Muri make

Ubwiza n'Iyubahirizwa ry'Amategeko
Ingano z'Ubuziranenge:
Ingano y'inganda: Ubuziranenge bwa ≥99.5%, bukwiriye gukorwa muri resin na plasticizer, bwujuje ibipimo bya ISO 9001.
Ingano y'imiti: Ikurikiza amabwiriza ya EP na USP yo gukoreshwa mu miti ikoreshwa mu buvuzi, ifite icyuma gikomeye ≤10 ppm.
Umutekano no Kuramba:
Byakorewe mu bigo byemewe na ISO 14001 hakoreshejwe oxidation ya catalytic ya o-xylene, hamwe na sisitemu zo kugarura ubushyuhe bw'imyanda kugira ngo bigabanye ubwinshi bwa karuboni.
Bipakiye mu mifuka ya kg 25 cyangwa amapaki ya kg 1000, byanditseho amabwiriza yo kwirinda ingaruka za GHS kugira ngo bifatwe neza kandi bifatwe neza (byemewe na IMDG/ADR).

Kuki twahitamo Anhydride yacu ya Phthalic?
Waba ukora ibikoresho bishya byo mu gisekuru gitaha, ugakora irangi rigezweho, cyangwa ugakora pulasitiki irambye, PA yacu itanga uburyo bwo gukora no gutunganya ibintu neza. Dufite ahantu ho gukwirakwiza ibicuruzwa ku isi hose muri Amerika ya Ruguru, i Burayi, na Aziya, dutanga serivisi zizewe kandi zigatera inkunga tekiniki kuva ku nganda nini kugeza ku mishinga y’ubushakashatsi yihariye.
