Hanyoyi da yawa na yin masana'anta na hydrophilic Nonwoven

Hydrophilic hanya ce ta gama gari don yadudduka marasa saƙa. Gabaɗaya, yadudduka marasa saƙa suna hana ruwa. Dangane da buƙatun, masana'antun suna aiwatar da pretreatment ko bayan jiyya akan yadudduka marasa saka, kuma waɗannan jiyya guda biyu suna shafar tasirin hydrophilic kai tsaye. A yau bari in kawo muku bambanci tsakanin riga-kafi da kuma bayan gyaran yadudduka na hydrophilic wadanda ba saƙa. Ina fatan zai iya taimaka muku!

Da farko dai, yadudduka da ba a saka ba suna hana ruwa, hydrophilic ba saƙar yadudduka da ruwa maras saƙa ya saba. Saboda masana'anta da ba a saka ba kanta ba ta ruwa ba, wajibi ne a ƙara hydrophilic masterbatch ko ƙara man fetur na hydrophilic don inganta yanayin hydrophilic na kayan da ba a saka ba, wato don inganta aikin hydrophilic.

Hydrophilic masana'anta da ba a saka ba yana da ikon ɗaukar ruwa, wato, rabon hydrophilic, saurin hydrophilic, lokutan hydrophilic, lokacin ingancin hydrophilic da lokuta. Domin inganta hydrophilicity na ba-saka yadudduka, shi ne kullum don inganta surface wettability don cimma burin hydrophilicity. A halin yanzu, hanyoyin masana'anta na masana'anta na hydrophilic waɗanda ba saƙa za su iya kasancewa ta hanyar gyare-gyaren jiki da gyare-gyaren sinadarai: gyare-gyaren haɗaɗɗen (watau kafin kadi) da gyaran ƙasa (watau bayan kadi).

1. Blending gyare-gyare (gyara kafin kadi)

Dangane da lokacin ƙara daban-daban na abubuwan da aka gyara, ana iya raba shi zuwa hanyar masterbatch, cikakken hanyar granulation da hanyar allura kafin kadi.

1. Common masterbatch hanya

Wannan hanya ce mai mahimmanci ga masana'antun da ba a saka ba don samar da kayan da ba a saka ba. Hydrophilic masterbatch an yi shi ne daga ƙari na hydrophilic gama gari ta masana'anta na masterbatch, sa'an nan kuma a haɗe shi da PP don narke masana'anta, wato masana'anta na hydrophilic mara saƙa.

Abũbuwan amfãni: sauƙin samarwa, babu buƙatar ƙara kowane kayan aiki, kuma ya dace da ƙananan samar da tsari. Bugu da ƙari, dagewar hydrophilic yana da ƙarfi.

2. Jimlar granulation

An shirya barbashi na PP na hydrophilic ta hanyar dunƙule extrusion granulation, sa'an nan kuma narke spud a cikin zane.

amfani; Kyakkyawan aiwatarwa, sakamako mai dorewa, za'a iya amfani da zane akai-akai.

3. Allura kafin kadi

An saka polymer hydrophilic kai tsaye cikin babban dunƙule na masana'anta mara saƙa kuma an haɗe shi da narke PP don jujjuya kai tsaye.

Abvantbuwan amfãni: sakamako mai dorewa, ana iya amfani da zane akai-akai

2. Surface hydrophilic kammala (gyara bayan kadi)

Ƙarshen hydrophilic hanya ce mai sauƙi, mai tasiri da ƙananan farashi don yin kayan da ba a saka ba. Babban tsarin fasaha shine kamar haka:

A kan layi spunbonded zafi-birgima maras saka yadudduka - Roll shafi ko spraying hydrophilic wakili - infrared ko zafi iska bushewa -- winder -- hydrophilic karewa maras saka membrane.

Abũbuwan amfãni: babu spinnability matsala, azumi hydrophilic sakamako, high dace da kuma low farashin da ba saƙa masana'anta, wanda shi ne 1 / 2-1 / 3 na kudin na kowa masterbatch hanya. Dace da taro samar.
