1. Cov khoom siv ntawmlub thawv ton hnab
Cov khoom siv feem ntau suav nrog polypropylene (PP) thiab polyethylene (PE), uas yog thawj qhov kev xaiv rau kev tsim cov pob zeb vim tias lawv cov khoom siv zoo heev thiab cov tshuaj tiv thaiv corrosion. Tsis tas li ntawd, muaj qee yam khoom siv xws li polyester thiab nylon uas tseem siv rau hauv cov ntawv tshwj xeeb.
Polypropylene (PP)
Polypropylene (PP) muaj lub zog tensile zoo heev thiab kev puas tsuaj, uas ua rau lub thawv ntim khoom kom ruaj khov thiab tsis yooj yim tawg thaum thauj khoom thiab thauj khoom hnyav. Nws cov tshuaj inertness ua rau PP zoo tiv taus rau feem ntau cov kua qaub, alkalis thiab cov kuab tshuaj organic, ua rau nws haum rau ntim cov khoom siv tshuaj. Tsis tas li ntawd, qhov tsawg ntom ntom ntawm PP ua rau nws hnav, yooj yim los tuav thiab khaws cia. PP kuj muaj kev ua haujlwm zoo, thiab tuaj yeem ua tiav rau hauv cov thawv ntawm ntau cov duab thiab cov lus qhia los ntawm kev xaws, txheej thiab xaws, thiaj li ua tau raws li cov kev xav tau ntawm cov neeg siv khoom sib txawv. Nws cov cua sov ua haujlwm thiab kev laus kuj ua rau FIBC ua los ntawm PP haum rau kev siv mus ntev hauv ntau yam kev nyab xeeb. PP yog ib puag ncig tus phooj ywg thiab rov ua dua tshiab, tab sis tseem yuav tsum tau ua tib zoo saib xyuas kom txo tau qhov cuam tshuam ntawm ib puag ncig hauv kev tsim khoom thiab rov ua dua tshiab.
Polyethylene (PE)
Ib qho ntawm qhov zoo tshaj plaws ntawm polyethylene (PE) yog nws qhov yooj yim heev thiab kev cuam tshuam, uas tso cai rau cov bales kom nqus cov quab yuam thaum thauj khoom thiab kev thauj mus los, txo qhov kev pheej hmoo ntawm kev tawg. Nws cov tshuaj inertness ua rau PE zoo tiv taus rau feem ntau cov kua qaub, cov hauv paus, thiab ntsev, ua rau nws zoo tagnrho rau kev siv hauv kev khaws cia thiab kev thauj mus los ntawm cov tshuaj. Kev ua haujlwm kub qis ntawm PE yog qhov zoo dua li ntawm PP, thiab nws tseem tuaj yeem tswj tau zoo toughness nyob rau hauv qhov chaw txias thiab tsis ua rau brittleness. Qhov tsawg ntom ntom ntawm PE ua rau cov bales loj ua los ntawm nws lub teeb hauv qhov hnyav thiab yooj yim los tuav thiab khiav lag luam. PE kuj muaj kev laus tiv thaiv zoo, thiab los ntawm kev ntxiv cov tshuaj tiv thaiv antioxidants thiab UV stabilizers, nws tuaj yeem txuas ntxiv lub neej kev pab cuam.thawv ton hnab.
2 Kev tsim cov txheej txheem ntawm cov pob ntau
Txheej txheem weaving
Cov txheej txheem weaving yog ib qho tseem ceeb tshaj plaws kev sib txuas hauv cov txheej txheem tsim khoom ntawmthawv ton hnab, uas ua lub luag haujlwm txiav txim siab hauv nws lub zog thiab ruaj khov, siv polypropylene (PP) lossis polyethylene (PE) ua cov khoom tseem ceeb, uas yog tsim rau hauv cov xov hlau tiaj tus los ntawm cov txheej txheem kos duab hlau, thiab tom qab ntawd cov xov hlau tiaj tiaj no tau woven rau hauv cov ntaub siv lub voj voog ncig. Txoj kev weaving ceev thiab txoj kev weaving ncaj qha cuam tshuam rau lub cev lub cev ntawm lub thawv ntim lub hnab. High-density weaving tuaj yeem txhim kho lub zog tensile thiab hnav tsis kam ntawm bulk bales, tab sis tib lub sijhawm, nws kuj nce cov khoom siv thiab cov nqi tsim khoom. Txhawm rau kom ua tiav qhov kev ua tau zoo tshaj plaws, tsim nyog weaving wensity thiab weaving wensity thiab weaving txoj kev, xws li satin weave, feem ntau yog siv los ua tiav qhov sib npaug ntawm lub zog thiab tus nqi. Nyob rau hauv cov txheej txheem weaving, nws tseem yuav tsum tau them sai sai rau lub uniformity thiab stability ntawm lub weaving txheej txheem kom tsis txhob muaj uneven weaving thiab ntaub defects, uas yuav txo tau cov bearing muaj peev xwm thiab kev pab cuam lub neej ntawm lub thawv ton hnab.
Txheej txheej txheej
Siv cov txheej txheem txheej txheej, cov khoom siv polypropylene (PP) lossis polyethylene (PE) yog coated rau saum npoo ntawm daim ntaub los ntawm cov khoom siv extrusion los ua ib zaj duab xis, uas tuaj yeem tiv thaiv kev nkag mus ntawm cov dej noo thiab tshuaj lom neeg, tiv thaiv cov khoom sab hauv. Nyob rau hauv txheej txheej txheej, lub thickness thiab uniformity ntawm txheej yog qhov tseem ceeb tswj tsis. Cov txheej txheej tuab tuaj yeem txhim kho cov dej thiab tshuaj lom neeg, tab sis ua kom cov nyiaj thiab cov nqi ntawm cov khoom; Ib txheej txheej nyias yuav tsis muab kev tiv thaiv txaus. Yuav kom ua tiav cov txiaj ntsig zoo tshaj plaws, txheej txheej thickness thiab uniformity yuav tsum tau nruj nruj tswj thaum lub sij hawm tsim khoom. Siv cov cuab yeej extrusion siab heev thiab tsis siv neeg tswj qhov system, cov txheej txheem txheej txheej siab tuaj yeem ua tiav.
