Yashnab wovenyog ua los ntawm polypropylene (PP) ua raw khoom, thiab yog tsim los ntawm extrusion, hlau kos duab, weaving, knitting thiab hnab ua.
Polypropylene yog translucent thiab semi-crystalline thermoplastic nrog lub zog siab, zoo rwb thaiv tsev, tsis tshua muaj dej nqus, siab thermoforming kub, tsawg ntom thiab crystallinity siab.Nws yog lub ntsiab raw khoom ntawm woven hnab.Hloov kho cov khoom siv feem ntau suav nrog cov iav fibers, cov khoom siv ntxhia, cov roj hmab thermoplastic, thiab lwm yam.
Cov hnab yas woven muaj ntau yam kev siv.Tam sim no, cov hnab yas woven tsuas yog siv rau kev ntim khoom ua liaj ua teb, ntim hnab ntim khoom noj, ntim khoom noj, geotechnical engineering, tourism kev thauj mus los, dej nyab cov ntaub ntawv, thiab lwm yam. Woven hnab feem ntau suav nrog cov hnab yas (cov hnab ntim tsis muaj zaj duab xis), cov hnab yas sib xyaw. hnab thiab ntau yam woven fabrics.Cov txheej txheem ntawm cov hnab yas woven yog raws li nram no: weave printing, txiav, thiab xaws rau hauv woven hnab.
Nyob ntawm cov khoom siv, nws tuaj yeem txiav ua ntej thiab tom qab ntawd luam tawm, lossis luam tawm thiab tom qab ntawd txiav.Tsis siv neeg tailors tuaj yeem ua tiav kev luam ntawv, txiav, xaws thiab lwm yam txheej txheem, thiab tseem tuaj yeem ua rau hauv lub hnab ntim valve, hauv qab hnab ris, thiab lwm yam. Rau cov ntaub qhwv dawb, lub hnab tuaj yeem ua los ntawm gluing qhov chaw seam.Cov txheej txheem ntau lawm ntawm cov hnab yas woven yog los ua ke los yog lub tsho woven fabrics, txheej ntaub ntawv thiab ntawv los yog zaj duab xis.Lub raj los yog daim ntaub tuaj yeem raug txiav, luam tawm, sewn thiab ua rau hauv ib lub hnab hauv qab seam, los yog xuas nrig ntaus, folded, txiav, luam tawm thiab sewn rau hauv ib lub hnab cement, thiab daim ntaub tau tuaj yeem xaws, gluing, printing, txiav thiab gluing rau hauv qab patch hnab ris.Nws tseem tuaj yeem welded thiab dov los ua tarpaulins thiab geotextiles.Cov ntaub ntawv dawb tuaj yeem coated lossis uncoated los tsim cov tarpaulins, geotextiles, thiab lwm yam, thiab cov ntaub cylindrical kuj tuaj yeem coated lossis uncoated los tsim tarpaulins lossis geotextiles, thiab lwm yam.
Cov txheej txheem kev qhia ntawm cov txheej txheem ca hlau ntau lawm feem ntau muab faib ua plaub pawg:
1. Mechanical Performance index.Feem ntau suav nrog tensile quab yuam, tus txheeb ze tensile quab yuam, elongation ntawm so, linear ceev, linear ceev sib txawv;
2. Lub cev thiab tshuaj hloov kho qhov ntsuas.Muaj kev sib xyaw ua ke ntawm kev hloov kho, kev sib xyaw ua ke, kev ua haujlwm ntxiv ntxiv piv, thiab kev sib xyaw ntawm cov khoom pov tseg thiab cov khoom siv rov ua dua tshiab;
3. Tolerance dimension Performance index.Muaj feem ntau tiaj hlau thickness, tiaj hlau dav thiab lwm yam.
4. Lub cev rheological Performance index.Muaj feem ntau cov qauv kev sib piv, qhov sib piv nthuav dav, qhov sib piv ntawm qhov sib piv thiab thim rov qab;
Cov khoom siv polyethylene hauv cov txheej txheem hauv lub hnab yog rhuab, yaj, yas thiab extruded stably los ntawm extruder;
Nyem rau hauv cylindrical zaj duab xis los ntawm lub taub hau tuag;qhia cov pa roj compressed kom nthuav dav rau cov npuas tubular;
Siv lub nplhaib cua txias kom txias thiab ua kom zoo, rub lub herringbone splint thiab quav nws;
Los ntawm traction rollers, tsav rollers thiab winding rollers,
Thaum kawg, cov txheej txheem txiav thiab cua sov sealing yog nqa tawm kom tiav cov khoom ntawm lub hnab hauv ob sab phlu, thiab thaum kawg lub hnab ntim.
Ntshiab polypropylene rau cov xov paj tiaj tiaj tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, thiab ib qho kev faib ua feem ntawm high-pressure polyethylene, calcium carbonate thiab xim masterbatch yuav tsum tau ntxiv.Ntxiv ib qho me me ntawm kev kub siab polyethylene tuaj yeem txo qhov viscosity thiab melting ceev ntawm cov khoom ntws thaum extrusion, ua kom lub fluidity, txhim kho lub toughness thiab softness ntawm lub tiaj xov xov thiab woven hnab, tuav ib tug tej yam elongation ntawm so, thiab txhim kho qhov tsawg. kub cuam tshuam ntawm polypropylene..
Qhov sib ntxiv ntawm grafted polypropylene tuaj yeem txo qhov ua haujlwm kub thiab siab.Txhim kho cov khoom ntws thiab adhesion, thiab txawm nce tensile zog.Qhov sib ntxiv ntawm calcium carbonate tuaj yeem hloov pauv qhov tsis xws ntawm pob tshab thiab opacity, txo cov teeb meem hluav taws xob zoo li qub uas tsim los ntawm kev sib txhuam thaum lub sij hawm ncab thiab xaws, ua rau kom tus number case adhesion ntawm cov qauv luam ntawv luam tawm, thiab txo lub ntuj shrinkage ntawm cov khoom tiav thaum khaws cia.
