Umehluko phakathi kokuhlunga kwendawo nokuhlunga okujulile

Okokusebenza kwesikrini kusetshenziselwa kakhulu ukusefa komhlaba kanye nezinto ezizwakalayo zisetshenziselwa ukuhlunga okujulile. Umehluko umi ngale ndlela elandelayo:

1. Okuqukethwe kwesikrini (i-nylon monofilament, i-monofilament yensimbi) ngqo kuhlangana nokungcola kokuhlunga ebusweni bento. Izinzuzo ukuthi isakhiwo se-monofilament singahlanzwa kaninginingi futhi izindleko zokusetshenziswa ziphansi; Kepha okungalungile yimodi yokuhlunga ebusweni, okulula ukudala ukuvimba kwendawo yesikhwama sesihlungi. Lolu hlobo lomkhiqizo lufaneleke kakhulu ezikhathini zokuhlunga amaqhafuqangi ngokunemba okuphansi, futhi ukunemba kokuhlunga kungu-25-1200 μ m.

2.Izinto ezibunjiwe (indwangu eshaywe ngenaliti, indwangu eshisiwe engalukwanga) iyinto ejwayelekile yokuhlunga enezinhlangothi ezintathu, ebonakala ngohlaka lwefayibha okuxekethile ne-porosity ephezulu, okwandisa umthamo wokungcola. Lolu hlobo lwezinto ze-fiber lungemodi yokuxuba okuhlanganisiwe, okungukuthi, izinhlayiya ezinkulu zokungcola ziyabanjwa ebusweni be-fiber, kuyilapho izinhlayiya ezinhle zibhajwe kusendlalelo esijulile sento yokuhlunga, ngakho-ke ukuhlunga kunokuhlunga okuphezulu ukusebenza kahle, Ngaphezu kwalokho, ukwelashwa kokushisa okuphezulu kwendawo yokushisa, okungukuthi, ukusetshenziswa kobuchwepheshe bokushesha osheshayo, kungavimbela ngempumelelo i-fiber ekulahlekelweni ngenxa yomthelela wejubane eliphezulu loketshezi ngesikhathi sokuhlunga; Izinto ezizwayo ziyalahlwa futhi ukunemba kokuhlunga kungu-1-200 μ m.

Izici eziyinhloko zezinto zokuhlunga ezizwayo zimi ngale ndlela elandelayo:

I-Polyester - ifayibha yokuhlunga esetshenziswa kakhulu, ukumelana okuhle kwamakhemikhali, izinga lokushisa elisebenza ngaphansi kuka-170-190 ℃

I-Polypropylene isetshenziselwa ukuhlunga oketshezi embonini yamakhemikhali. Inokumelana okuhle kwe-acid ne-alkali. Ukushisa kwayo okusebenzayo kungaphansi kuka-100-110 ℃

Uboya - umsebenzi omuhle we-solvent solvent, kepha awufanelanga i-anti acid, ukuhlunga kwe-alkali

INilong inokumelana okuhle kwamakhemikhali (ngaphandle kokumelana ne-asidi), futhi ukushisa kwayo okusebenzayo kungaphansi kuka-170-190 ℃

I-fluoride inomsebenzi omuhle kakhulu wokumelana namazinga okushisa nokumelana namakhemikhali, kanti izinga lokushisa elisebenzayo lingaphansi kuka-250-270 ℃

Ukuqhathanisa okuhle nokubi phakathi kwento yokuhlunga ebusweni nezinto zokuhlunga ezijulile

Kunezinhlobo eziningi zezinto zokuhlunga zezihlungi. Njengokwelukiweyo wocingo, iphepha lokuhlunga, ishidi lensimbi, isici sokuhlunga esenziwe sintered futhi wazizwa, njll. Kepha, ngokusho kwezindlela zayo zokuhlunga, ingahlukaniswa ngezinhlobo ezimbili, okuyi-surface type nohlobo lokujula.

1. Izinto zokuhlunga ezingaphezulu
Izinto zokuhlunga zohlobo lwaphezulu zibizwa nangokuthi izinto zokuhlunga eziphelele. Ingaphezulu lalo linejometri ethile, ama-micropores afanayo noma iziteshi. Isetshenziselwa ukubamba ukungcola emafutheni okuvimba. Okokuhlunga kuvame ukuhlunga okucacile noma okuluhlaza okwenziwe ngocingo lwensimbi, indwangu yensimbi noma ezinye izinto. Umgomo wayo wokuhlunga uyefana nokusetshenziswa kwesikrini ngokunemba. Ukunemba kokuhlunga kuncike kubukhulu bejiyometri bama-micropores neziteshi.

Izinzuzo zohlobo lokuhlunga lendawo ebusweni: ukubonakaliswa okunembile kokunemba, anhlobonhlobo wohlelo lokusebenza. Kulula ukuhlanza, ukusebenza kabusha, impilo ende yokusebenza.

Ububi bezinto zokuhlunga zohlobo lwendawo zimi kanje: inani elincane lokungcola; Ngenxa yomkhawulo wobuchwepheshe bokukhiqiza, ukunemba kungaphansi kwe-10um

2. Izinto zokuhlunga ezijulile
Ukujula kohlobo lokuhlunga okubizwa nangokuthi izinto zokuhlunga zohlobo olujulile noma okokuhlunga kohlobo lwangaphakathi. Izinto zokuhlunga zinokuqina okuthile, okungaqondakala njengokuphakanyiswa kwezihlungi eziningi zohlobo lwendawo. Isiteshi sangaphakathi asakhiwa ngobukhulu obujwayelekile futhi abunasayizi othile wegebe elijulile. Lapho uwoyela udlula ezintweni zokuhlunga, ukungcola okukuwoyela kuyabanjwa noma kukhangiswe ekujuleni okuhlukile kwento yokuhlunga. Ukuze udlale indima yokuhlunga. Isihlungi sephepha kuyinto ejwayelekile yokuhlunga impahla esetshenziswa ohlelweni lokubacindezela. Ukunemba kuvame ukuba phakathi kuka-3 no-20um.

Izinzuzo zohlobo olujulile lokuhlunga impahla: inani elikhulu lokungcola, impilo ende yenkonzo, ekwazi ukususa izinhlayiya eziningi ezincane kunokunemba nokuhluba, ukunemba kokuhlunga okuphezulu.

Okubi kwezinto zokuhlunga zohlobo lokujula: abukho usayizi ofanayo wegebe lezinto zokuhlunga. Ubukhulu bezinhlayiya zokungcola abakwazi ukulawulwa ngokunembile; Cishe akunakwenzeka ukuyihlanza. Iningi lazo liyalahlwa. Ukusetshenziswa kukhulu.
