Yiziphi izinhlobo zezinto ezenziwe nge-laminated nonwoven zezimoto?

Izinto ezingalukiwe ezenziwe nge-laminated

Ukugcoba kuyinqubo lapho ukuncibilika kwe-polymer kufakwa ku-substrate ngomshini wokumboza, bese yomiswa ukuze kwakhiwe ifilimu yokuzivikela ebusweni be-substrate. Amafilimu aphezulu e-polymer ngokuvamile i-polyethylene, i-polypropylene, noma i-polyester, futhi ahlukaniswe abe amafilimu asekelwe emanzini namafilimu asekelwe ku-oyela ngokusekelwe kuzici zawo. Ubuchwepheshe bokumboza obusekelwe emanzini buncibilikisa ama-polymer aphezulu emanzini, bese bemboza i-solvent ebusweni bendwangu, futhi ekugcineni bukhiqize ungqimba oluvikelayo lwe-substrate ngokusebenzisa ukomiswa kwe-infrared noma ukomiswa kwemvelo. I-solvent esetshenziswa kubuchwepheshe bokugcoba okusekelwe kuwoyela ikakhulukazi i-UV photosensitive resin, engomiswa kuphela ngemisebe ye-ultraviolet. Ungqimba olunamafutha anokumelana okuhle nokungqubuzana futhi lungasetshenziswa isikhathi eside ezindaweni ezihlukahlukene zemvelo noma ze-physicochemical ezifana ne-infrared, i-ultraviolet, i-laser, umoya, isithwathwa, imvula, iqhwa, i-asidi ne-alkali.

Izinto ezingezona ezilukiwe ezenziwe nge-laminated zilungiswa ngokumboza izinto ezingezona ezilukiwe ezincibilika noma ezincibilikisa i-polymer ephezulu, futhi zingaba ngesimo se-single-layer noma i-double-layer coatings, njengoba kuboniswe kuMfanekiso 1 no-Figure 2. Isendlalelo sokumboza singanikeza amandla athile futhi sibophe imicu engaphezulu ye-substrate, icindezele ukushelela okuhlangene phakathi kwezinto ezibonakalayo, futhi ithuthukise izakhiwo ze-compos. Ngesikhathi esifanayo, ukusebenzisa izici zesendlalelo sokumboza kungaphinda kunikeze impahla ngamanzi namafutha axosha izinto.

Izinhlobo ze-laminated nonwoven materials

Njengamanje, ama-substrates asetshenziselwa ukusetshenziswa okukhulu kwezinto ezingezona ezilukiwe ezilamiwe ikakhulukazi izinto ezingalukiwe ezigoqwe ngenaliti kanye nezinto ezingalukiwe ezenziwe nge-spunbond, ezinye zisebenzisa izinto ezingalukiwe ezine-hydroentangled.

Inaliti elaminethiwe ngesibhakela impahla nonwoven

Izinto ezingalukiwe ezinenaliti ezibhontshiwe zenziwe ngemicu enezinhlangothi ezintathu ezinesakhiwo esinezinhlangothi ezintathu, ezinikeza izindwangu ezingalukiwe ezinezinaliti ezikwazi ukungena kahle nokusebenza kahle kokuhlunga. Phakathi nenqubo yokubumba, inaliti ibhoboza ngokuphindaphindiwe i-fiber web, iphoqelela imicu engaphezulu nasendaweni ingene ngaphakathi kwewebhu. Iwebhu yasekuqaleni ethambile iyacindezelwa, inikeze inaliti ebhontshiwe ngendwangu engalukiwe kahle kakhulu. Ukwemboza ingaphezulu yenaliti ngenqindi izinto ezingezona nokwelukiweyo nge ungqimba polymer ifilimu ungqimba oluncibilikisiwe ifilimu kungaba ukungena ingaphakathi impahla, ngcono amandla esiyinhlanganisela enamathela ifilimu [5]. Ngenaliti ye-fiber enezingxenye ezimbili ezwiwe, ifilimu encibilikisiwe yakha izibopho ezengeziwe nemicu, okwenza ukwakheka kwezinto ezibonakalayo kuhlangane kakhudlwana .

Izinto ezingalukiwe ezenziwe nge-spunbond

Izindwangu ezingalukiwe ze-Spunbond zinezakhiwo ezinhle kakhulu ezifana namandla aphezulu, indawo ebushelelezi, ukuzwa kwesandla esithambile, nokumelana nokugoba nokuguga, futhi zisetshenziswa kakhulu ezindwangu zezimoto. Imicu yangaphakathi ye-spunbond nonwoven materials iboshelwa ngokuqinile ezindaweni ezigoqayo, futhi ungqimba lwe-polymer oluphezulu lufafazwa phezu kwempahla. Ifilimu encibilikisiwe kulula ukuyihlanganisa nemicu kanye namaphoyinti aginqikayo wempahla ye-spunbond, ithuthukisa ukusebenza okuphelele kwempahla engalukiwe ye-spunbond elaminate.

I-laminated hydroentangled nonwoven material

Indlela yenqubo yokwenza izinto ezingezona ezilukiwe ezinama-hydroentangled ukuthi ijethi yamanzi enengcindezi ephezulu kakhulu ithinta i-fiber web, ibangele ukuthi imicu engaphakathi kwe-fiber web ibambene futhi yakhe into eqhubekayo engalukiwe ngaphansi komthelela wendiza yamanzi. Izinto zejethi zamanzi ezingalukiwe zinezakhiwo ezinhle zokuthamba nokunwebeka. Uma kuqhathaniswa nenaliti eqinile ebhontshiwe izinto ezingalukiwe, amandla enaliti yamanzi aba buthakathaka, okuholela ekuthandeni okuphansi phakathi kwemicu engaphakathi enalithi yamanzi ebhontshiwe into engalukiwe, okuyenza iphefumule kangcono. Ngokusebenzisa ubuchwepheshe bokumboza ifilimu, ungqimba lwefilimu ye-polymer ewuketshezi oluphezulu lumbozwa phezu kwezinto ezisetshenziswayo ze-jet nonwoven zamanzi, ezingahlinzeki nje ngokusebenza okuhle kakhulu kokuvikela ifilimu, kodwa futhi zinokuguquguquka okuhle nokunwebeka okuqinile.

I-Dongguan Liansheng Non woven Technology Co., Ltd.yasungulwa ngoMeyi 2020. Kuyibhizinisi elikhulu lokukhiqiza indwangu engalukiwe ehlanganisa ucwaningo nentuthuko, ukukhiqiza, nokudayiswa. Ingakwazi ukukhiqiza imibala ehlukahlukene ye-PP spunbond izindwangu ezingalukiwe ezinobubanzi obungaphansi kwamamitha angu-3.2 ukusuka ku-9 amagremu kuya ku-300 amagremu.
