Ngā koparehe papanga kore-whatu, he papanga kore-whatu tēnei, he rerekē ki ngā papanga kakahu, ā, he mea tito mai i ngā muka ahunga, muka matapōkere rānei.
Ko ngā kopare hauora he hanganga maha-paparanga, e kiia ana ko ngā hanganga SMS (2 S me te 1 M paparanga). I tēnei wā, ko te maha o ngā paparanga i Haina ko te 5, arā, ko te SMMMS (2 S paparanga me te 3 M paparanga).
He aha te karere kuputuhi?
I konei, ko te S e tohu ana i te paparanga Spunbond. He matotoru te whānui o te muka, tata ki te 20 maikorona (m). Ko te mahi matua o ngā paparanga Spunbond e 2 ko te tautoko i te hanganga papanga kore-whatu katoa, kāore he pānga nui ki te ārai. Ko te wāhanga nui rawa atu o te kopare ko te paparanga ārai, ko te paparanga Meltblown M rānei (paparanga Meltblown). He angiangi te whānui o te paparanga rehu rewa, tata ki te 2 maikorona (M), nō reira he kotahi tekau noa iho o te whānui o te paparanga spunbond, he mea nui ki te aukati i te huakita me te urunga toto.
Ko ngā kopare hauora whānui he kakahu rehu rewa te taumaha, 20 karamu te taumaha, ko ngā kopare kapu N95 he kakahu rehu rewa te taumaha, 40 karamu neke atu rānei.
E ai ki ngā tatauranga a te China Industrial Textile Industry Association, i te mutunga o te tau 2018, e 1,477 ngā raina whakaputa miro ā-rohe, e 65 te nui ake i tērā o te tau o mua, me te pikinga tau-ki-te-tau o te 4.6%, i roto i ēnei, kua piki ake te raina whakaputa miro kore-whatu PP mā te 3.38%, te raina whakaputa hiato SMS mā te tata ki te 13%, me te raina whakaputa miro kore-whatu PET mā te 9.32%. Kua piki ake hoki te maha o ngā kamupene he nui ake te putanga ā-tau i te 50,000 tana mai i te tau 2017. Kei te tere haere ngā umanga miro kore-whatu i tā rātou whanaketanga ki te tauine, te whakanui me te taumata-teitei hei whakatutuki i te hiahia o te mākete mō te whakapai ake i ngā hua me te whakapai ake i ngā hangarau.
Mai i te tau 2018, he maha ngā umanga ā-rohe kua whakawhanake i ā rātou hua kia māmā ake, kia angiangi ake, kia teitei ake te mahi, ā, kua tutuki ngā hua pai. Kei te puta tonu mai ngā hua kounga pumau, he tukanga whakakotahitanga SSMMS spunbonded/melten shotcreting 600m/min neke atu rānei, he tere teitei te mahi; Tata ki te 10 karamu ia mita tapawha, he tino ngohengohe, he mārama, he kounga pumau.
Nō hea te papanga kore-whatu SMS?
Ngā papanga kore-whatu SMShe mea hanga te nuinga mai i te polypropylene PP (me ngā āhuatanga bacteriostatic taiao me te hydrophobicity), ā, ka taea e te diameter o ngā muka te eke ki te 0.5-10 microns. Ka whakanui ake ēnei muka tino pai me te capillary ahurei i te nui me te horahanga mata o ngā muka mō ia horahanga, ā, ka pai ake ngā āhuatanga tātari hau o ngā papanga rehu-rewa, ka waiho hei rauemi kopare pai.
I tēnei wā, e toru ngā tukanga matua mō te hanga hua SMS (kakahu kore-whatu SMS): "tukanga kotahi-taahiraa", "tukanga rua-taahiraa" me te "tukanga kotahi-me-te-hawhe-taahiraa".
Ko ngā āhuatanga kotahi-taahiraa ko te whakamahinga o ngā rauemi mata o tēnei tukanga, mā te whakamahi i ngā hangarau miro-hono e rua, pupuhi-rewa, ka miro tika ngā rauemi mata i muri i te rewa ki roto i ngā kupenga, mena he whakaritenga tika o ngā tukanga rerekē o te miihini pūnaha miro, ā, ka taea te hanga hua me te hanganga rerekē, ia paparanga papanga whakakikoruatia, ko te tikanga he whakakotahi ki roto i te kakahu me te mira hurihuri wera. Ko te "tikanga kotahi-taahiraa" e tohuhia ana e te rewa tika ki roto i te kupenga, ka taea te whakarite motuhake i te āhua o ia pūnaha miro, he kaha te mana whakahaere o te tukanga whakaputa, he pai te hauora, he tere teitei, ka taea te whakarite i te ōwehenga o ia paparanga kupenga muka, ka taea te whakaputa hua momo SMS o ngā whakaritenga rerekē, koinei te hangarau matua o ēnei rā.
Tukanga rua-taahiraa: Ina whakamahia te tukanga rua-taahiraa hei whakaputa hua SMS, ka wetekina ngā hua kua oti o te kakahu miro me te kakahu rehu-rewa i roto i tētahi raupapa, kātahi ka pania i roto i tētahi raupapa, kātahi ka whakakotahi ki te mira wera, ka whakakotahi hei hua SMS. Ko te tikanga rua-taahiraa he māmā noa ngā taputapu me te iti o te utu. Inaa, ko te tukanga "rua-taahiraa" te hangarau whakakotahi whakapiri e whakamahia whānuitia ana, engari ka taea hoki te whakakotahi i ētahi atu rauemi, me ngā rauemi rerekē, me ngā tikanga rerekē, pērā i te ultrasonic, te whakapiri rewa wera e toru ngā paparanga o ngā rauemi e hono ana.
Tikanga kotahi-me-te-hawhe: i roto i te tikanga e rua-hawhe, ka taea hoki te whakakapi i te hua kakahu rehu rewa ki te apa rehu rewa kupenga muka i hangaia i te mara, nā reira i puta ai te tukanga hiato "tikanga kotahi-hawhe-hawhe". Ka whakamahia te kakahu miro hei paparanga raro me te paparanga mata e ngā taputapu wetewete e rua, ā, ka miro tika te kupenga muka rehu rewa o te paparanga waenga ki roto i te kupenga e te pūnaha rehu rewa, ka whakatakotoria ki runga i te paparanga raro o te kakahu miro, kātahi ka hipokina ki te paparanga o runga o te kakahu miro, he pai ake te whakamahi i te mira wera kua whakakotahihia ki ngā hua SMS.
