A na-eji akwa polypropylene (PP) eme ihe n'ọtụtụ ebe n'ihi arụmọrụ ya dị mma, ụzọ nhazi dị mfe, na ọnụ ala dị ala. Karịsịa n'ime afọ ndị na-adịbeghị anya, a na-eji ya eme ihe n'ọtụtụ ebe dị ka nlekọta ahụike, uwe, ihe nkwakọ ngwaahịa, ihe nhicha, ihe mkpuchi ọrụ ugbo, geotextiles, ihe nzacha ụlọ ọrụ, wdg, ma nwee usoro iji dochie ihe ọdịnala ya.
N'ihi usoro na-abụghị polar nke PP, nke na-enweghị otu hydrophilic, PP na-abụghị nke a kpara akpa enweghị isi ọrụ ntinye mmiri. Mgbanwe ma ọ bụ imecha hydrophilic dị mkpa iji mepụta akwa na-abụghị nke PP hydrophilic.
I. Ụzọ maka ịkwadebe hydrophilic na-abụghị akwa akwa
Iji melite hydrophilicity nke PP nonwoven akwa, a na-enwekarị ụzọ abụọ iji melite ha elu wettability: anụ ahụ mgbanwe na chemical mgbanwe.
Mgbanwe kemịkalụ na-agbanwekarị usoro nke PP ma na-agbakwunye otu hydrophilic na agbụ macromolecular, si otú ahụ gbanwee hygroscopicity ya. Enwere ụzọ dị ka copolymerization, grafting, cross-linking, na chlorination.
Mgbanwe nke anụ ahụ na-agbanwekarị usoro dị elu nke ụmụ irighiri ihe iji melite hydrophilicity, tumadi site na ngbanwe mgbanwe (tupu ịtụgharị) na mgbanwe elu (mgbe agbachara).
II. Mgbanwe agwakọtara (mgbanwe tupu mgbanwe)
Dabere na oge mgbakwunye dị iche iche nke mgbakwunye gbanwetụrụ, enwere ike kewaa ha n'ime usoro masterbatch, usoro granulation zuru oke, na usoro ịgbanye ihe nkpuchi mkpuchi.
(1) Usoro masterbatch agba nkịtị
Nke a bụ ụzọ dị mkpa maka ịmepụta akwa hydrophilic na-abụghị nke ndị na-emepụta ihe na-emepụta ihe.
Nke mbụ, ndị na-emepụta osisi na-eme ihe mgbakwunye hydrophilic nkịtị ka ọ bụrụ irighiri mmiri jellyfish, wee jikọta ya na PP na-atụgharị ka ọ bụrụ akwa akwa.
Uru: Mfepụta dị mfe, ọ dịghị mkpa ịgbakwunye ngwá ọrụ ọ bụla, kwesịrị ekwesị maka obere mmepụta nke anụ ụlọ, na mgbakwunye na ike hydrophilic siri ike.
Ọdịmma: Hydrophilicity dị nwayọ na arụ ọrụ nhazi adịghị mma, nke a na-ejikarị akwa akwa. Ọnụ ego dị elu, 2 ruo 3 ugboro dị elu karịa mgbanwe elu.
Ogbenye spinnability chọrọ mmezi nke usoro. Ụfọdụ ndị ahịa furu efu tọn 5 nke ákwà si na ụlọ ọrụ masterbatch abụọ agba agba na-emepụtaghị ngwaahịa emechara.
(2) Usoro granulation zuru oke
Gwakọta ihe na-agbanwe agbanwe, mpekere PP, na ihe mgbakwunye n'otu n'otu, gbanye ha n'okpuru ịghasa iji mepụta akụkụ nke PP hydrophilic, wee gbazee ma tụgharịa ha n'ime akwa.
Uru: Ezi nhazi nhazi, mmetụta na-adịte aka, na akwa ákwà eji eme ihe.
Mwepu: A na-achọ ihe mgbakwunye screw extruder ọzọ, na-ebute ọnụ ahịa dị elu kwa ton na nwayọọ nwayọọ hydrophilicity, na-eme ka ọ dị mma maka mmepụta nnukwu.
(3) Fangqian injection
Tinye ngwa ngwa hydrophilic reagents, ntụgharị hydrophilic polymers, na isi ịghasa nke akwa anaghị kpara akpa wee gwakọta ha na PP gbazere maka ịgbanye ozugbo.
Uru: Mmetụta na-adịte aka na akwa nwere ike ijikwa ya ọzọ.
Ihe ọghọm: N'ihi enweghị ike ịgwakọta nke ọma, ịgbagharị na-esikarị ike ma enweghị mmegharị.
III. Ngwucha hydrophilic dị n'elu (mgbe ọ gachara ọgwụgwọ)
Ịmecha hydrophilic bụ ụzọ dị mfe, dị irè na nke dị ọnụ ala maka ịmepụta akwa akwa na-abụghị nke hydrophilic. Ọtụtụ n'ime ndị na-emepụta akwa anyị anaghị kpara akpa na-eji usoro a. Isi usoro bụ nke a:
Online spunbond na-ekpo ọkụ akpọrepu akwa na-abụghị kpara - roller mkpuchi ma ọ bụ mmiri spraying hydrophilic agent - infrared ma ọ bụ ikuku na-ekpo ọkụ
Uru: Ọ dịghị spinnability okwu, ngwa ngwa hydrophilic mmetụta nke na-abụghị kpara akwa, elu arụmọrụ, ala price, ọ bụ 1 / 2-1 / 3 nke na-eri nke nkịtị agba masterbatch. Kwesịrị ekwesị maka mmepụta ihe dị ukwuu;
Mwepu: Ọ na-achọ ka ịzụrụ ihe dị iche iche post-processing, nke dị oke ọnụ. Mgbe ịsachara ugboro atọ, oge ntinye mmiri na-abawanye ihe dịka ugboro iri na ise. Enweghi ike imezu ihe a choro maka imeghari;
Mmepụta oke;
Uru na ọghọm dị na usoro a na-ekpebi na a na-ejikarị ya eme ihe maka ngwaahịa ndị a na-atụfu ihe na-achọ nnukwu permeability na hydrophilicity, dị ka ihe dị ọcha, akwa akwa, akwa akwa nhicha, wdg.
ⅣIji usoro mgbagwoju anya Hydrophilic Particle PPS03
N'ịtụle uru na ọghọm dị n'ụzọ (-) na (ii) ụzọ, e mepụtara ihe mejupụtara nne hydrophilic PPS030.
Ụdị jeliifish a nwere njirimara nke usoro onunu ogwu (dị ka ihe jeliifish nkịtị), mmetụta ngwa ngwa, mmetụta na-agbasa ngwa ngwa, mmetụta dị mma, mmetụta na-adịte aka, ezigbo nguzogide ịsa ahụ, mana ọnụ ahịa dị elu (dị ka akụkụ jellyfish nkịtị).
Ezi spinnability, ọ dịghị mkpa ịgbanwe mmepụta usoro.
Kwesịrị ekwesị maka imepụta obere ogbe yana nguzogide ịsacha dị elu, ngwaahịa ndị a na-eji eme ihe dị ka ọhịa na akwa ugbo.
Ihe ngosi nyocha bụ isi nke hydrophilic PP akwa na-abụghị nke a kpara akpa gụnyere ntinye mmiri, akụkụ kọntaktị, na mmetụta capillary.
(1) Ọnụ nnabata mmiri: na-ezo aka na oke mmiri na-etinye n'otu akụkụ nke akwa hydrophilic nonwoven n'ime oge ọkọlọtọ ma ọ bụ oge achọrọ iji mee ka ihe ahụ zuru oke. Ka mmụba mmiri na-abawanye, mmetụta ahụ ka mma.
(2) Usoro nkuku kọntaktị: Debe akwa hydrophilic PP na-abụghị nke a kpara akpa n'elu efere iko dị ọcha ma dị nro, dọba ya n'elu oven, hapụ ya ka ọ gbazee. Mgbe agbazechara, wepụ efere iko ahụ ma mee ka ọ dị jụụ ruo n'ime ụlọ. Jiri ụzọ nnwale ozugbo tụọ akụkụ kọntaktị nha nha nha. Obere akụkụ kọntaktị, ka mma. (PP na-enweghị kpara akwa na-enweghị ọgwụgwọ hydrophilic mgbe ọ ruru ihe dịka 148 Celsius).
