Chii Is "Isina kurukwa"" ?
Kana wakamboshandisa chifukidzo chemeso, chipunu chemvura, kana bhegi rekutenga, wabatajira risina kurukwa. Asi heino nyonganyonga: haina kumonereka, haina weft, haina shinda, uye haina kuruka. Jira rechinyakare rinoda kumonereka nekuruka—matanho maviri makuru. Isina kurukwa inodarika ese ari maviri. Fibers (kana purasitiki yakanyungudutswa) inoiswa zvakananga mudandemutande, yozobatanidzwa pamwe chete nekupisa, kukweshana, kana makemikari anonamira. Muna 2022, China yakagadzira matani mamiriyoni 8.29 ayo—anopfuura chikamu chimwe muzvitatu chehuwandu hwepasi rose. Ndiyo chikamu chiri kukura nekukurumidza mumachira, chaizvo nekuti hachina basa ne "machira" zvachose.
Meltblown: Super-Filter
Kunyungudukainotanga nema polypropylene pellets, ayo anonyungudutswa uye anoburitswa kuburikidza nema nozzles madiki. Kuputika kwemhepo inopisa ye200‑300°C kunotambanudza kunyunguduka kuita microfibers ine ukobvu hwe 1‑5 microns chete—mamwe akatsetseka se 0.5 microns. (Vhudzi remunhu rinosvika 70 microns.) Idzi shinda dzakatetepa kwazvo dzinogadzira maze yakakora, inokombama inobata mabhakitiriya, madonhwe, uye zvidimbu. Ndosaka chikamu chepakati che mask yekuvhiya chichifanira kunyungudutswa. Chinonyanya kukosha: inomhanya ne 1‑5 m/min chete, inonzwa isina kusimba, uye inodhura $3,500‑5,500 patani—mutengo wakapetwa kaviri kusvika katatu kupfuura mamwe asina kurukwa. Saka haumbozvioni wega; inogara iri gamba rakavanzika rakaiswa pakati pezvikamu zvakasimba.
Spunbond: Bhiza Rinoshanda
Spunbond inonyungudutsawo polymer, asi inoburitsa tambo dzinoramba dzichishandiswa dzine ukobvu hwema microns 15-35—dzakakora uye dzakasimba. Kana yatambanudzwa nemhepo yoiswa pabhandi rinofamba, dandemutande rinosungirirwa pakupisa nemaroller anopisa. Mugumisiro wacho: jira rakasimba, rinodzivirira kubvaruka rinomhanya pa50-500 m/min (kusvika 1,000 m/min pamitsetse yekumhanya kwakanyanya)—rinokurumidza ka100 kupfuura meltblown. Kuderedza kumhanya ikoko kunodhura kusvika ku$1,700-2,800 patani. Spunbond ibhegi rako rezvekudya, chifukidziro chekurima, fenicha, uye majasi ekudzivirira ekunze. Yakachipa uye yakasimba, asi yakaoma uye yakaita sepurasitiki—haisi chinhu chaungade kupukuta kumeso kwako nacho.
SMS: Zvirinani Pamwe Chete
Zvigadzirwa zvepasi rose hazviwanzo sarudza nzira imwe chete. Iyo yekare SMS-spunbond/meltblown/spunbond-inosanganisa zvakanakisa zvezvose zviri zviviri. Majasi ekurapa anoshandisa spunbond yekunze kudzivirira zvinwiwa, meltblown yepakati kubata zvidimbu, uye spunbond yemukati kuti inyaradze.chifukidzo chekuvhiyazvakafanana: chikamu chekunze chinodzinga mapombi, meltblown inobata mavhairasi, uye chikamu chemukati chinotora hunyoro. Kunyangwe machira akawanda emvura anosanganisa chikamu chakapfava che spunlace nechigadziko chakasimba che spunbond. Maitiro ega ega ane kushaya simba; kusanganisa kwakangwara kunoita kuti pave nekushanda pasina kuputsa mari.
Haasi Ese Matanda Asina Kurukwa Akagadzirwa Akaenzana
Isina kurukwaZviri kwese kwese - mamasiki, machira ekupukuta, mabhegi, mafirita, magown - asi vanhu vazhinji havazivi kuti meltblown inobva kupi. Zvino wava kuziva: unoda kusefa here? Enda ku meltblown. Unoda simba uye mutengo wakaderera here? Spunbond ndiyo mhinduro yako. Uye kana ukaona SMS, uri kutarisa sandwich yakagadzirwa zvakanaka. Zita rimwe chete rekuti "jira", mashandiro akasiyana zvikuru - uye musiyano wemutengo wakapetwa kashanu. Kunzwisisa nzira idzi hakuzoiti kuti uve nyanzvi yemachira, asi kuchakuita mutengi akangwara.
