Lub hnab ntim yas yog ua los ntawm polypropylene (PP) ua cov khoom siv tseem ceeb, uas yog extruded, hlau kos, rov woven, woven, thiab ua rau hauv hnab ntim.
PP yog lub pob tshab, semi-crystalline thermosetting yas nrog lub siab toughness, zoo rwb thaiv tsev zog, tsis tshua muaj dej nqus, siab ambient kub, tsis tshua muaj txheeb ze ceev, thiab siab iav kub.Nws yog cov khoom siv tseem ceeb rau kev ua cov hnab ntim khoom.Hloov cov ntaub ntawv muab tub lim feem ntau suav nrog iav fibers, cov khoom siv ntxhia, cov roj hmab thermoplastic, thiab lwm yam.
Lub peev xwm ntawm kev siv cov hnab yas ntim khoom yog dav heev.Nyob rau theem no, cov ntawv thov tseem ceeb ntawm cov hnab ntim cov hnab yas yog cov khoom ntim sab nrauv ntawm cov khoom ua liaj ua teb, cov khoom ntim sab nrauv ntawm cov hnab yas woven, cov khoom ntim khoom noj, geological engineering, hnub so tourism kev thauj mus los, dej nyab thiab cov khoom siv thaum muaj xwm ceev, thiab lwm yam. Cov hnab ntim khoom tseem ceeb: hnab ntim cov hnab yas (cov hnab ntim tsis muaj zaj duab xis), cov hnab ntim khoom sib xyaw thiab ntau lub hnab ntim khoom.Cov txheej txheem tsim cov hnab yas ntim khoom yog: cov hnab ntim khoom ua cov hnab ntim tom qab ntim thiab luam ntawv, laser txiav thiab xaws.
Nyob ntawm lub tshuab thiab cov cuab yeej siv, nws tuaj yeem ua laser txiav thiab luam tawm, lossis luam tawm thiab tom qab ntawd laser txiav.Tsis siv neeg laser txiav tshuab xaws tuaj yeem txuas ntxiv cov txheej txheem ntawm ntim luam ntawv, laser txiav, tshuab xaws, thiab lwm yam, thiab tseem tuaj yeem ua rau hauv cov hnab ris valve, hauv qab hnab ris, thiab lwm yam. lub hnab tuaj yeem ua tau.Cov txheej txheem tsim khoom ntawm cov hnab ntim khoom sib xyaw yog siv cov hnab ntim khoom, cov pob zeb sib xyaw lossis cov yeeb yaj kiab rau kev sib koom ua ke lossis cov txheej txheem sib xyaw.Cov tau yob los yog cov ntawv thiab yob tuaj yeem yog laser txiav, ntim thiab luam tawm thiab phais stitched los ua cov hnab seam hauv qab.Lawv tuaj yeem qhib qhov, ntug crimping, laser txiav, ntim ntawv luam ntawv, phais stitching thiab hnab yas woven.Cov ntawv tau tuaj yeem muab khi nrog seam, pob luam ntawv, laser txiav, lub hau kev sib txuas thiab lub hnab ntim khoom.Nws tseem tuaj yeem welded, tso, crimped, ua rau hauv ntoo los thiab tsis-woven geotextiles.Flat looms tuaj yeem rov ua dua lossis tsis rov ua dua thiab tsim khoom, tsis yog-woven geotextiles, thiab lwm yam. Lub nruas daim ntaub kuj tuaj yeem tsim dua los yog tsis.
Cov kev ntsuas kev ua tau zoo ntawm cov yas xaim kos duab tshuab tsim cov txheej txheem feem ntau muab faib ua plaub pawg:
1. Lub cev Performance index tus nqi.Feem ntau muaj qhov yuam kev xws li tawg quab yuam, tus txheeb ze tawg quab yuam, tensile lub zog, angular tshaj tawm, thiab ceev;
2. Index qhov tseem ceeb ntawm cov organic chemically hloov cov ntaub ntawv.Nws feem ntau suav nrog kev sib xyaw cov ntaub ntawv hloov kho, kev npaj sib xyaw, ntxiv qhov piv ntawm cov hloov pauv, thiab qhov piv ntawm cov khib nyiab regenerated granular compound fertilizer;
3. Dimensional kam rau ua specification index tus nqi.Nws feem ntau suav nrog cov tuab ntawm cov yas hlau kos duab tshuab thiab qhov dav ntawm lub tiaj tus hlau.
4. Lub cev muaj zog rheological index tus nqi.Muaj feem ntau cov xov paj splitting ratio, inflation ratio, draft ratio thiab shrinkage ratio;
Lined bag processing technology Kev kub siab polyethylene khoom yog rhuab los ntawm extruder, melted thiab extruded smoothly;
Nias cov yas zoo li lub thoob rau hauv cov yeeb yaj kiab zoo li lub thoob;nkag mus kom txo tau cov plua plav tshuab thiab ua rau cov npuas npuas;
Lub herringbone-shaped plaub hau straightening splint yog txias thiab zoo li lub nplhaib cua txias, thiab cov traction yog coj mus rau hauv kev hloov dua siab tshiab;
Lub tshuab hluav taws xob cov menyuam yog rub mus rau cov menyuam winding los ntawm txoj siv traction roller;
Thaum kawg, laser txiav yog nqa tawm, lub hnab hauv ob sab phlu yog tsim los ntawm cov txheej txheem kub-kua, thiab thaum kawg cov txiv hmab txiv ntoo yog bagged.
Ntshiab polypropylene tsis tuaj yeem ua tau raws li cov kev xav tau ntawm cov yas xaim kos duab tshuab, tab sis nws kuj yuav tsum tau ntxiv qee feem pua ntawm polyethylene, calcium bicarbonate thiab xim masterbatch.Ntxiv ib qho me me ntawm polyethylene thaum lub sij hawm tag nrho cov txheej txheem extrusion tuaj yeem txo qhov viscosity thiab melting tus nqi ntawm cov khoom ntws, txhim kho fluidity, txhim kho cov ductility thiab saj zawg zog ntawm cov yas xaim kos duab tshuab thiab cov hnab ntim yas, tuav lub zog tensile, thiab txhim kho polypropylene ultra-low kub puas.
Kev txhim kho polypropylene additives tuaj yeem txo qhov kub thiab txias thiab ua haujlwm siab hauv kev tsim khoom thiab kev ua haujlwm ib puag ncig.Txhim kho cov ntaub ntawv ntws thiab adhesion, txhim kho tensile lub zog.Qhov sib ntxiv ntawm calcium bicarbonate tuaj yeem hloov qhov tsis txaus ntawm kev ua tiav pob tshab thiab opacity.Hauv kev txo qis, tag nrho cov txheej txheem ua rau muaj kev puas tsuaj rau electrostatic induction vim nws muaj kev cuam tshuam rau kev sib txhuam, txhim kho luam ntawv number case adhesion rau ntim thiab luam ntawv cov cim logos, txo cov kev sau ntuj thiab tswj cov nqi ntawm cov khoom tiav thaum khaws cia.
