Khaub ncaws tuam ntxhab feem ntau sau PAN ua ib feem ntawm lawv cov khoom xyaw. Dab tsi yog tsis paub rau txhua tus. PAN stands rau polyacrylonitrile, los yog, nyob rau hauv cov lus dawb, acrylic ntaub. Lub npe no muaj ntau dua thiab paub rau cov neeg siv khoom.
PAN khoom yam ntxwv
Acrylic fabrics yog cov khoom siv ruaj khov tshaj plaws. Lawv zam lub hnub ncaj qha thiab los nag zoo. PAN yog cov khoom siv hluavtaws zoo, cov khoom siv raw rau kev tsim khoom ntawm cov roj derivatives, uas yog cov tshuaj polyacrylonitrile. Nyob rau hauv kev ua lag luam, xws li fabrics hu ua acrylic, orlon, nitron thiab ntau lwm lub npe.
PAN cov khoom siv
PAN yog cov khoom uas nws muaj pes tsawg leeg thiab zoo li cov ntaub plaub, uas yog vim li cas acrylic feem ntau hu ua cov ntaub plaub tsiaj. PAN yog cov xov sov, mos, lub teeb thiab pliable uas yuav tsis raug mob los ntawm npauj. Nws yuav tsum raug sau tseg, yam ntxwv ntawm cov khoom siv PAN, tias nws yog cov khoom siv zoo acrylic, uas tuaj yeem khaws nws cov duab raws li kev ua haujlwm ntawm cov tshuaj ntxuav thiab vagaries ntawm xwm. Nws yog yuav luag tsis raug rau fading thiab discoloration, nws yog ib qho yooj yim muspleev xim rau, yog li cov khoom ci ci thiab saturated xim.
Nws tseem tsim nyog sau cia, thaum piav qhia txog cov khoom siv PAN, qhov no tsis yog qhov zoo tshaj plaws fiber ntau, txawm tias tag nrho cov txiaj ntsig, vim tias pellets tsim rau ntawm nws, cov ntaub tsis dhau huab cua zoo, ua hluav taws xob, poob nws. elastic zog nyob rau hauv lub siab kub thiab nyhav rau oily av uas nyuaj rau ntxuav.
khoom siv
PAN fiber ntau yog tsim los siv cov cuab yeej hauv qab no:
- Ua fiber ntau-forming polymer.
- ntub lossis qhuav fiber ntau shaping.
- Regenerated nrog cov kuab tshuaj (dimethylformamide los yog dimethylacetamide).
Polyacrylonitrile yog tus yam ntxwv ua cov thermoplastic ntawm pawg thib ob, uas nyob rau hauv txoj kev xav tuaj yeem raug fused nyob rau hauv cov huab cua kub. Tab sis tib lub sij hawm, thermal puas ntawm fiber ntau yog ua tau - ib tug txheej txheem nyob rau hauv uas radicals yog tsim. Tsis tas li ntawd, cov nyhuv ntawm cov cua kub tam sim no yog qhov sib sib zog nqus, uas ua rau kom tiav melting ntawm cov ntaub thiab nws hardening. Yog li ntawd, rau kev sib txuas zoo ntawm acrylic fabrics, kub gluing yog siv.
Fiber daim ntawv thov
PAN yog cov khoom siv uas nws lub zog tso cai rau nws siv dav rau hauv kev lag luam. Nws yog siv rau hauv kev tsim khoom ntawm:
- yarn;
- fabrics;
- ntaub;
- rooj tog zaum;
- knitwear;
- faux fur;
- paj;
- nonwovens(geotextile).
PAN - cov khoom uas nws muaj pes tsawg leeg tsim kom muaj kev ntxhib los mos thiab tsis muaj qhov ci, yog qhov zoo rau kev tsim cov ntawv tshaj tawm lossis kos npe, awning lossis canopy.
Lub ci ntsa iab thiab lub zog ntawm fiber ntau, uas tsis ntshai ntawm qhov txias lossis cua sov, tso cai rau koj ua cov khoom zoo, suav nrog cov ris tsho hauv qab thiab ris tsho hauv qab. PAN yog cov khoom siv zoo tagnrho rau cov khaub ncaws, feem ntau ntxiv rau cov ntaub plaub los yog mohair los txhim kho kev ua haujlwm. Cov khoom sib xyaw ua ke tsis yog tsuas yog muaj lub ntsej muag zoo nkauj, tab sis kuj muaj qhov hnav tsis kam tsis poob nws qhov qub.
Cov ntaub ntaub ua los ntawm acrylic tsis plam xim saturation txawm tias raug tshav ntuj ntev ntev.
Yuav tu li cas rau cov khoom siv acrylic
Peb tuaj yeem hais tau nyab xeeb, tau kawm cov khoom siv PAN, tias cov fiber ntau no tsis tas yuav muaj kev txawj tshwj xeeb rau kev saib xyuas. Cov khoom siv acrylic tuaj yeem ntxuav thiab ntxuav nrog tshuaj, ua raws li cov cai.
- Tshuab thiab ntxuav tes yog pom zoo nyob rau hauv dej sov thiab ntxiv cov pab yaug mus rau dej kawg. Kev raug kub hnyiab tuaj yeem ua rau cov khoom poob nws cov softness thiab zoo.
- Tej yam uas ua los ntawm PAN fiber ntau tsis pom zoo kom wring tawm thiab qhuav nyob ib puag ncig ntawm cov khoom siv cua sov tam sim ntawd. Nws yog qhov zoo tshaj los tso cov khoom ncaj nraim rau ntawm qhov chaw tiaj tus rau saum cov phuam.
- Iron tej khoom yuav tsum yog los ntawm moistened gauze.
- Tsis yog txhua yam khoom siv acrylic tuaj yeem ntxuav kom qhuav. Cov ntaub ntawv hais txogqhov no yog teev rau ntawm daim ntawv lo.
Txawm tias qhov tseeb tias cov khoom siv PAN yog hluavtaws, nws qhov zoo yog siab heev. Thiab yog tias cov khoom tsim los ntawm cov fiber ntau tau siv kom raug thiab saib xyuas zoo, lawv yuav ua haujlwm ntev heev yam tsis tau poob lawv cov yam ntxwv zoo.
