Mubikorwa byo kubyaza umusaruro udoda, ibintu bitandukanye bishobora kugira ingaruka kumiterere yibicuruzwa.
Isesengura ryibintu byingenzi bigira ingaruka kumiterere yimyenda ifasha kugenzura neza imikorere yimikorere no kubona PP nziza idahwitse idafite ubuziranenge bwiza kugirango ihuze abakiriya.
1.Ubwoko bwa polipropilene: gushonga indangagaciro n'uburemere bwa molekile
Ibipimo ngenderwaho byingenzi byibikoresho bya polypropilene nuburemere bwa molekuline, gukwirakwiza uburemere bwa molekile, isotacticity, gushonga hamwe nibirimo ivu.
Abatanga polipropilene bari murwego rwo hejuru rwurunigi rwa plastiki, batanga ibikoresho fatizo bya polypropilene kumanota atandukanye.
Gukora spunbond idoda, uburemere bwa polypropilene mubusanzwe buri hagati ya 100.000-250.000.Nyamara, byagaragaye ko umutungo ushonga ukora neza mugihe uburemere bwa molekile bugera ku 120000. Umuvuduko ntarengwa wo kuzunguruka nawo uri hejuru kururu rwego.
Icyerekezo cyo gushonga nikintu cyerekana imiterere ya rheologiya yo gushonga.Igipimo cyo gushonga cya PP ya spunbond mubusanzwe iri hagati ya 10 na 50.
Indanganturo ntoya yo gushonga ni, uko amazi arushaho kuba mabi, ni nako igipimo cyo gutegura ari gito, kandi nini nini ya fibre iyo imeze nkibisohoka bimwe biva muri spinneret, bityo kudoda byerekana ibyiyumvo bikomeye byamaboko.
Iyo indangururamajwi nini, ubwiza bwashonga buragabanuka, umutungo wa rheologiya uza neza, kandi imyiteguro yo kurwanya iragabanuka.Muburyo bumwe bwo gukora, gutegura byinshi biriyongera.Hamwe no kwiyongera kwicyerekezo cya macromolecules, imbaraga zo kumena zidoda zizanozwa, kandi ingano yintambara izagabanuka, kandi imyenda izumva yoroshye.Mu nzira imwe, urwego rwo hejuru rwo gushonga, imbaraga zo kuvunika zikora neza .
Ubushyuhe bwo kuzunguruka
Igenamiterere ry'ubushyuhe buzunguruka biterwa no gushonga kw'ibikoresho fatizo n'ibisabwa ku bintu bifatika.Urwego rwo hejuru rushonga rusaba ubushyuhe bwo kuzunguruka, naho ubundi.Ubushyuhe bwo kuzunguruka bufitanye isano itaziguye no gushonga.Bitewe n'ubukonje bwinshi bwo gushonga, biragoye kuzunguruka, bikaviramo kuvunika, gukomera cyangwa gukomera kwinshi, bigira ingaruka kumiterere yibicuruzwa.
Kubwibyo, kugirango ugabanye ubukonje bwashonga no kunoza imiterere ya rheologiya yo gushonga, kongera ubushyuhe muri rusange.Ubushyuhe bwo kuzunguruka bugira uruhare runini ku miterere n'imiterere ya fibre.
Iyo ubushyuhe bwo kuzunguruka bushyize hejuru, imbaraga zo kumena ziba nyinshi, kuramba kumeneka ni bito, kandi imyenda ikumva yoroshye.
Mu myitozo, ubushyuhe bwo kuzunguruka busanzwe bushiraho 220-230 ℃.
3. Igipimo cyo gukonja
Muburyo bwo gukora ibizunguruka, igipimo cyo gukonjesha umugozi kigira uruhare runini kumiterere yumubiri wa sponbonded nonwovens.
Niba fibre yakonje gahoro gahoro, ibona imiterere ihamye ya kirisiti ya monoclinike, idafasha fibre gushushanya.Niyo mpamvu, muburyo bwo kubumba, uburyo bwo kongera umwuka ukonje no kugabanya ubushyuhe bwicyumba kizunguruka bikoreshwa mugutezimbere kumena imbaraga no kugabanya kurambura imyenda idoze.Mubyongeyeho, intera ikonje yintambara nayo ifitanye isano ya hafi nimiterere yayo.Mu gukora imyenda idoze idoda, intera ikonje muri rusange iri hagati ya cm 50 na cm 60.
4. Gutegura ibisabwa
Icyerekezo cyurwego rwimikorere ya molekile muri filament nikintu cyingenzi kigira ingaruka kumeneka ya monofilament.
Uburinganire hamwe no kumena imbaraga za spunbonded nonwovens zirashobora kunozwa mukongera amajwi yumuyaga.Ariko, niba ingano yumwuka mwinshi ari nini cyane, biroroshye kumena umugozi, kandi umushinga urakabije, icyerekezo cya polymer gikunda kuba cyuzuye, kandi kristu ya polymer ni ndende cyane, bizagabanya u Ingaruka imbaraga no kurambura kuruhuka, no kongera ubwitonzi, bigatuma kugabanuka kwimbaraga no kurambura imyenda idoda.Birashobora kugaragara ko imbaraga no kuramba bya sponbonded nonwovens byiyongera kandi bigabanuka buri gihe hamwe no kwiyongera kwumwuka wumwuka.Mu musaruro nyirizina, inzira igomba guhinduka ukurikije ibikenewe hamwe nuburyo nyabwo kugirango tubone ibicuruzwa byiza.
5. Ubushyuhe bukabije
Urubuga rumaze gushushanya, rurarekuye kandi rugomba guhuzwa no kuzunguruka.Urufunguzo ni ukugenzura ubushyuhe nigitutu.Igikorwa cyo gushyushya ni koroshya no gushonga fibre.Ikigereranyo cya fibre yoroshye kandi yahujwe igena imiterere yumubiri ya PP spunbond idoda.
Iyo ubushyuhe butangiye hasi cyane, gusa agace gato ka fibre ifite uburemere buke bwa molekile yoroheje kandi igashonga, fibre nkeya ihujwe hamwe mukibazo. kurambura ni binini, kandi umwenda wumva woroshye ariko birashoboka guhinduka fuzz;
Iyo ubushyuhe bushyushye bwiyongereye, ubwinshi bwa fibre yoroshye kandi yashonge byiyongera, urubuga rwa fibre ruba ruhujwe cyane, ntabwo byoroshye kunyerera.Imbaraga zo kumena imyenda idoda iriyongera, kandi kurambura biracyari binini.Byongeye kandi, kubera isano ikomeye hagati ya fibre, kurambura byiyongera gato;
Iyo ubushyuhe buzamutse cyane, imbaraga zidoda zitangira kugabanuka, kurambura nabyo bigabanuka cyane, urumva umwenda uba ukomeye kandi ugacika intege, kandi imbaraga zamarira zikagabanuka. Kubintu bito byubushyuhe buke, hariho fibre nkeya kumwanya ushushe kandi muke ubushyuhe bukenewe mu koroshya no gushonga, bityo ubushyuhe buzunguruka bugomba gushyira munsi.Mu buryo buhuye, kubintu byimbitse, ubushyuhe bushyushye buri hejuru.
6. Umuvuduko ushushe
Muburyo bwo guhuza ibishyushye bishyushye, imikorere yumurongo ushushe wumurongo wumurongo nugukora fibre yoroshye kandi yashonze ihuza hamwe, byongera ubumwe hagati ya fibre, kandi bigatuma fibre itanyerera kunyerera.
Iyo umuvuduko ushyushye wumurongo ugereranije ni muke, ubwinshi bwa fibre ahakanda ni muke, kwihuta kwa fibre ntikuba hejuru, kandi guhuza fibre ni bibi.Muri iki gihe, ikiganza cyunva imyenda idoda idoze iroroshye, kurambura kuruhuka ni binini, ariko imbaraga zo kumena ni nke;
muburyo bunyuranye, iyo umuvuduko wumurongo uri hejuru cyane, ikiganza cyunvikana kumyenda idoda idoze iragoye, kandi kurambura kuruhuka ni bike Ariko imbaraga zo kumena ni nyinshi.Igenamigambi ryumuvuduko ushushe rifite byinshi byo gukora hamwe nuburemere nubunini bwimyenda idoda.Kugirango ubyare ibicuruzwa byujuje ibyangombwa bisabwa, birakenewe guhitamo igitutu gikwiye gishyushye ukurikije ibikenewe.
Mu ijambo, imiterere yumubiri yimyenda idoda ni ibisubizo byimikoranire yibintu byinshi.Nubwo umubyimba umwe umwe, gukoresha imyenda itandukanye birashobora gusaba inzira zitandukanye zikoranabuhanga. Niyo mpamvu abakiriya offen basabwe gukoresha imyenda.Bizafasha utanga isoko tegura umusaruro ufite intego yihariye kandi utange umukiriya mukundwa umwenda wuzuye udoda.
Nkumushinga wimyaka 17, Fuzhou Heng Hua New Material Co., Ltd.bizeye gutanga imyenda ukurikije ibyo abakiriya bakeneye.Twagiye twohereza mu bihugu n'uturere dutandukanye kandi twashimiwe cyane nabakoresha.
Murakaza neza mutugishe inama kandi mutangire ubufatanye burambye na Henghua Nonwoven!
