Ndeipi nzira yekusarukwa sefa midhiya yevasina-yakarukwa vanogadzira machira?

Kusefa kwemhepo nemvura kwakakosha kuhutano hwedu nekuchengetedzeka. Mafirita anouya mumhando uye nehukuru hwakasiyana uye anogona kugadzirwa kubva kumachira kana asina-kurukwa machira anogadzirwa nevasina kurukwa vanogadzira machira.

Machira akarukwa evagadziri vemachira asina kurukwa anogadzirwa nekuruka shinda imwe chete senge monofilament kana shinda yefayibha pachirukiso. Maitiro ekugadzira machira asiri akarukwa nevagadziri vemachira asiri akarukwa anosanganisira zvakatevedzana kana zvisina tsarukano kubatanidza faibha pamwe chete, uyezve kubatanidza imwe neimwe dhizaini yejira risiri rakarukwa nepolymer kuti riite porous zvinhu zvakakodzera kusefa.

Nzira dzakasiyana dzekugadzira sefa midhiya uchishandisa machira asiri akarukwa

Nzira yekugadzira yefilter mediazvakanyanya zvinoenderana nerudzi rwesefa inodiwa. Pane kunyanya nzira nhanhatu:

1. Kuronga nzira

Iyo yekusefa svikiro yemakina emakadhi yagara ichishandiswa kumasiki uye kusefa mafuta anodyika, mafuta ekutonhodza, uye mukaka. Vagadziri vemachira vasina kurukwa vanowanzoshandisa resin kana thermal bonding, iyo inogona kutsiviwa nedzimwe nzira dzinotsanangurwa pazasi mune dzimwe nguva.

2. Wet process

Mvura uye yakanyorova sefa midhiya inoshandiswa pakushambira mafirita, mafirita ekofi, uye mafirita emhepo. Kugadzira kwayo kwakafanana nekugadzira mapepa. Pamidziyo yakajairwa yekugadzira mapepa, musanganiswa wezvakagadzirwa, zvechisikigo, kana girazi faibha mapfupi fiber anoumba pepa repakati.

3. Melt blown nzira

Meltblown sefa midhiya isarudzo yakanakira kusefa kwechidimbu, senge huruva, asbestos, uye utsi. Iyi imhando yakajairika yemasefa mune zvinofema zviri nyore kugadzira kuwanda. Inoumbwa pasina kushandiswa kwefibers: panzvimbo pacho, polymer yakanyungudutswa inoputirwa mune microporous network.

4. Spunbond nzira

Spunbond sefa midhiya ikareruka uye inogona kushandiswa kufefeta mweya uye mvura. Vagadziri vemachira asina kuruka vanokuudza kuti senge media inonyungudutswa, haidi faibha, asi inorukwa kubva naironi, polyester, kana polypropylene.

5. Acupuncture

Kugadzirwa kwetsono yakabaiwa sefa midhiya ibasa remuchina rinosanganisira kushandiswa kwetsono dzakanzwa tsono kutsvaga uye kuvharira mafiibhi mu spunbond kana combing webs. Iwo matatu-dimensional chimiro chepinhole sefa midhiya ndiyo yakanakira sefa yekubata pamusoro uye mukati mezvikamu. Iyi inzira inowanzoshandiswa yekusefa yekuchenesa mvura inouya nemvura yetsvina.

6. Composite nzira

Zvisiri zvakarukwa zvakaumbwa inzira yekubatanidza akawanda akaturikidzana emachira asiri akarukwa nemapolymers pamwechete vachishandisa hunyanzvi hwakasiyana, nekudaro kubatanidza zvimiro zvega rega. Vagadziri vemachira vasina kurukwa vanokuudza kuti kuisa isarudzo yakanaka yekudziya, kutonhora, uye kufefetedza mudzimba, zvivakwa, uye mota panguva yekugadzira mafirita midhiya.

Zvakanakira Musanganiswa Musanganiswa

Mugadziri wemachira asina kurukwainokuudza kuti kana uchienzaniswa nedzimwe nzira, maitiro ekugadzirwa kwecompositi yemasefa midhiya ane zvakawanda zviri pachena zvakanakira. Mushure mekusanganiswa, zvinhu zvinova:

1. Kukwanisa kutsungirira kusauraya utachiona uye kuchenesa kwemakemikari akasimbiswa;

2. Kugadzikana kwakanaka kwepamusoro-tembiricha;

3. Pfeka zvisingaite uye uve nehupenyu hurefu hwebasa;

Dongguan Liansheng Non woven Technology Co., Ltd.yakavambwa muna Chivabvu 2020. Ibhizimusi rekugadzira jira rakakura risingarukwe rinobatanidza tsvakiridzo nekusimudzira, kugadzira, uye kutengesa. Inogona kuburitsa mavara akasiyana-siyana ePP spunbond machira asiri akarukwa ane hupamhi husingasviki 3.2 metres kubva pa9 gramu kusvika 300 magiramu.
