Qhov zoo
CPP
Non-toxic, compoundable, zoo dua nyob rau hauv pob tshab tshaj PE, thiab me ntsis inferior nyob rau hauv hardness. Kev ntxhib los mos yog mos, nrog lub pob tshab ntawm PP thiab softness ntawm PE.
PP
Lub hardness yog qis dua rau OPP, nws tuaj yeem ncab (ob txoj kev ncab) tom qab tau ncab rau hauv daim duab peb sab, hauv qab foob lossis sab foob
PE
Muaj formalin, tab sis lub pob tshab yog me ntsis tsis zoo

OPP
Zoo pob tshab thiab muaj zog hardness
Lub hnab ntim khoom
Lub foob muaj zog, luam tau, thiab tus number case yuav tsis poob
Co-extrusion hnab
Zoo pob tshab, mos zoo nkauj, luam tawm
Lub hnab ntim cov hnab yas tuaj yeem muab faib ua cov khoom sib txawv thiab siv tau: hnab yas woven thiab hnab yas zaj duab xis
Woven hnab
Cov hnab yas woven yog tsim los ntawm polypropylene hnab thiab polyethylene hnab raws li cov ntaub ntawv tseem ceeb;
Raws li txoj kev xaws, nws muab faib rau hauv qab hnab nrog seams thiab hauv qab hnab nrog seams.
Nws yog dav siv los ua cov khoom ntim rau cov chiv, cov khoom siv tshuaj thiab lwm yam khoom. Cov txheej txheem tseem ceeb yog siv cov khoom siv yas los extrude zaj duab xis, txiav, thiab uniaxially stretch mus rau hauv lub tiaj filaments, thiab ces weave cov khoom los ntawm warp thiab weft, uas feem ntau hu ua woven hnab.
Nta: lub teeb yuag, siab zog, corrosion kuj, thiab lwm yam., tom qab ntxiv cov yas zaj duab xis hauv ob sab phlu, nws tuaj yeem ua kom tsis muaj dej thiab noo noo pov thawj; Lub teeb lub hnab ntim qis dua 2.5kg, nruab nrab lub hnab ntim yog 25-50kg, hnyav lub hnab ntim yog 50-100kg
Hnab zaj duab xis
Cov khoom siv raw ntawm cov hnab yas zaj duab xis yog polyethylene. Cov hnab yas tiag tiag tau coj kev yooj yim rau peb lub neej, tab sis qhov yooj yim ntawm lub sijhawm no tau ua rau muaj kev phom sij ntev.
Muab faib los ntawm cov khoom siv: high-pressure polyethylene hnab yas, low-pressure polyethylene hnab yas, polypropylene hnab yas, polyvinyl chloride hnab yas, thiab lwm yam.
Muab faib los ntawm cov tsos: lub hnab T-shirt, lub hnab ncaj. Cov hnab ntim khoom, hnab yas strip hnab, hnab tshwj xeeb zoo li tus, thiab lwm yam.
Nta: Lub teeb lub hnab ntim ntau tshaj 1kg; nruab nrab hnab load 1-10kg; hnyav hnab load 10-30kg; Lub hnab ntim khoom thauj ntau tshaj 1000kg.
