Udupfukamunwani imyenda idaboshye, ikaba ari imyenda idaboshye itandukanye n'imyenda y'imyenda, kandi igizwe n'imigozi y'icyerekezo cyangwa iy'uburyo butandukanye.
Udupfukamunwa two kwa muganga muri rusange ni imiterere ifite amashami menshi, ikunze kwitwa imiterere ya SMS (imiterere ya S 2 na M 1). Ubu, umubare munini w'imiterere mu Bushinwa ni 5, ari byo SMMMS (imiterere ya S 2 na M 3).
SMS ni iki?
Aha, S isobanura urwego rwa Spunbond. Umurambararo w'umugozi ni munini cyane, hafi mikoroni 20 (m). Akamaro k'ingenzi k'urwego rwa 2 S Spunbond ni ugushyigikira imiterere yose y'imyenda idafunze, ibyo bikaba bitagira ingaruka zikomeye ku rukuta. Igice cy'ingenzi cya mask ni urwego rw'urukuta cyangwa urwego rwa Meltblown M (urwego rwa Meltblown). Umurambararo w'urwego rwa spray rushongeshejwe ni muto cyane, hafi mikoroni 2 (M), bityo ni kimwe cya cumi cy'umurambararo w'urwego rwa spunbond, rugira uruhare runini mu gukumira bagiteri no kwinjira mu maraso.
Udupfukamunwa two kwa muganga dusanzwe dukoresha igitambaro cyo gushonga gipima garama 20, udupfukamunwa two mu gikombe cya N95 dukoresha igitambaro cyo gushonga gipima garama 40 cyangwa zirenga.
Dukurikije imibare y’ishyirahamwe ry’inganda z’imyenda mu Bushinwa, mu mpera za 2018, hari imirongo 1.477 ikora ibikoresho byo mu rugo, 65 irenga iyo mu mwaka ushize, aho 4.6% byiyongereyeho umwaka ushize, muri yo, umurongo wa PP ukora ibikoresho byo mu bwoko bwa non-woven wongereweho 3.38%, umurongo wa SMS ukoze hafi 13%, naho umurongo wa PET ukoze ibikoresho byo mu bwoko bwa non-woven wongereweho 9.32%. Umubare w’ibigo bifite umusaruro urenga toni 50.000 ku mwaka na wo wiyongereye ugereranije n’umwaka wa 2017. Ibigo bikora ibikoresho byo mu bwoko bwa spunbonded birimo kwihutisha iterambere ryabyo bigana ku rwego rwo hejuru, kwiyongera no ku rwego rwo hejuru kugira ngo bihuze n’isoko ry’ibicuruzwa no kuvugurura ikoranabuhanga.
Kuva mu 2018, ibigo byinshi byo mu gihugu byateje imbere ibicuruzwa byabyo mu rwego rwo koroshya, gukata no gukora neza, kandi byageze ku musaruro mwiza. Uburyo bwo gukora bukozwe mu buryo bwa SSMMS spunbonded/molten shotcreting bukoresha umuvuduko mwinshi wa metero 600/minota cyangwa hejuru y’umuvuduko mwinshi; Hafi garama 10 kuri metero kare ibicuruzwa byiza kandi bihamye bikomeje kugaragara.
Ese umwenda utari uwo kuboha uturuka he kuri SMS?
SMS: imyenda idafunzeBikorwa cyane cyane muri polypropylene PP (ifite ubushobozi karemano bwo kurwanya bagiteri no kudahumeka), kandi umurambararo w'imigozi ushobora kugera kuri mikoroni 0.5-10. Iyi migozi myiza cyane ifite capillarity yihariye yongera ingano n'ubuso bw'imigozi kuri buri gice cy'ubuso, bityo bigatuma imyenda ishongeshejwe ikagira ubushobozi bwiza bwo kuyungurura umwuka, bigatuma iba ibikoresho byiza byo gupfuka.
Ubu, hari inzira eshatu z'ingenzi zo gukora ibicuruzwa bya SMS (SMS idafunze): "intambwe imwe", "intambwe ebyiri" na "intambwe imwe n'igice".
Intambwe imwe ni ugukoresha igice cy'ibikoresho fatizo muri ubu buryo, hakoreshejwe ikoranabuhanga rigizwe n'ibice bibiri bishongeshejwe, bishongeshejwe, ibikoresho fatizo bizingururwa mu buryo butaziguye nyuma yo gushonga mu miyoboro, igihe cyose hateguwe neza uburyo butandukanye bwo gukora imashini zizunguruka, kandi bishobora gukora ibicuruzwa bifite imiterere itandukanye, buri mwenda ukozwe mu buryo bwa laminated, ubusanzwe uhuzwa n'icyuma gishyushye gihuza imyenda. "Uburyo bw'intambwe imwe" burangwa no gushonga mu buryo butaziguye mu muyoboro, imiterere ya buri buryo bwo gushonga ishobora guhindurwa ku giti cyayo, inzira yo gukora igenzura rikomeye, ubuzima bwiza, umuvuduko mwinshi, ishobora guhindura igipimo cya buri rwego rw'umuyoboro wa fibre, ishobora gukora ibicuruzwa byo mu bwoko bwa SMS bifite ibisobanuro bitandukanye, ni ikoranabuhanga rizwi cyane muri iki gihe.
Intambwe ebyiri: Iyo ukoresheje inzira y'intambwe ebyiri mu gukora ibicuruzwa bya SMS, ibicuruzwa byarangiye by'imyenda ya spunbonned n'imyenda yashongeshejwe birazingururwa mu buryo runaka, hanyuma bigashyirwamo laminate mu buryo bumwe, hanyuma bigahuzwa n'icyuma gishyushya, bigashyirwamo ibicuruzwa bya SMS. Uburyo bw'intambwe ebyiri burangwa n'ibikoresho byoroshye kandi bihendutse. Mu by'ukuri, inzira y'"intambwe ebyiri" ni ikoranabuhanga rikoreshwa cyane mu gusya, ariko kandi rishobora kuba urusobe rw'ibindi bikoresho, hamwe n'ibindi bikoresho bitandukanye, kandi hakoreshejwe uburyo butandukanye, nka ultrasound, gusya bishyushye hamwe ibice bitatu by'ibikoresho.
Uburyo bw'intambwe imwe n'igice: mu buryo bw'intambwe ebyiri, birashoboka kandi gusimbuza igicuruzwa cy'imyenda ishongeshejwe n'urushundura rwa fibre rushongeshejwe rukorerwa mu murima, bityo hagakorwa uburyo bwitwa "uburyo bw'intambwe imwe". Igitambaro cya spunbonded gikoreshwa nk'urwego rwo hasi n'urwego rwo hejuru n'ibikoresho bibiri byo kwimura, kandi urushundura rwa fibre rushongeshejwe rw'urwego rwo hagati ruzungurutswa mu rushundura hakoreshejwe sisitemu yo gusukura, rugashyirwa ku rwego rwo hasi rw'igitambaro cya spunbonded, hanyuma rugapfundikirwa n'urwego rwo hejuru rw'igitambaro cya spunbonded, ni byiza gukoresha icyuma gishyushye gihujwe n'ibicuruzwa bya SMS.
