He aha Is "Kore-whatu" ?
Mena kua whakamahia e koe he kopare kanohi, he tauera mākū, he putea hokohoko rānei, kua pā atu koe kipapanga kore-whatuEngari anei te rerekētanga: kāore he whenu, kāore he miro, kāore he miro, kāore hoki he whatu. Me miro me te whatu te kakahu tuku iho—e rua ngā mahi nui. Kāore e taea te peke i ngā mea e rua i te mea kore-whatu. Ka whakatakotoria tika ngā muka (te kirihou rewa rānei) ki roto i te tukutuku, kātahi ka honoa ngātahi mā te wera, te waku, te whakapiri matū rānei. I te tau 2022, i hangaia e Haina te 8.29 miriona tana o taua mea—neke atu i te hautoru o te katoa o te ao. Koinei te rāngai tino tere te tipu o ngā kakahu, nā te mea kāore e aro ki ngā "kahu".
Meltblown: Te Tātari Tino Pai
Rewa-pūpūKa tīmata ki ngā pire polypropylene, ka rewahia, ka tukuna mā roto i ngā pūwero ririki. Ka totoro te hau wera 200‑300°C i te rewa ki roto i ngā muka moroiti he 1‑5 maikorona te matotoru—ko ētahi he angiangi ki te 0.5 maikorona. (Tata ki te 70 maikorona te matotoru o te makawe tangata.) Ka hangaia e ēnei muka tino angiangi he arai matotoru, he pikopiko e hopu ana i ngā huakita, ngā pata, me ngā matūriki. Koia te take me pupuhi te paparanga waenga o te kopare pokanga. Ko te raruraru: ka oma i te 1‑5 m/min anake, he pakarukaru te āhua, ā, he $3,500‑5,500 te utu mō ia tana—e rua ki te toru ngā wā he nui ake te utu i ētahi atu mea kore-whatu. Nō reira, kāore koe e kite i a ia anake; ko te toa huna tonu kei waenganui i ngā paparanga kaha ake.
Spunbond: Te Hōiho Mahi
Ka whakarewahia hoki e te Spunbond te pūmua, engari ka puta ake ngā miro tonu he 15‑35 maikorona te matotoru—he nui ake te matotoru, he kaha ake. Mēnā ka totorohia te tukutuku ki te hau, ka whakatakotoria ki runga i te whitiki neke, ka herea te tukutuku ki te wera mā roto i ngā roera wera. Ko te hua: he papanga pakari, ātete-roimata e oma ana i te 50‑500 m/min (tae atu ki te 1,000 m/min i runga i ngā raina tere-rahi)—100 ngā wā tere atu i te rewa-pūhia. Mā taua tere ka whakaitihia ngā utu ki te $1,700‑2,800 ia tana. Ko te Spunbond tō putea hoko kai, te uhi ahuwhenua, te arai tāonga, me te paparanga o waho o ngā kākahu tiaki. He iti te utu, he pakari, engari he maro, he kirihou—ehara i te mea e hiahia ana koe ki te horoi i tō mata.
Karere Kupu: Pai ake te mahi tahi
Kāore i te maha ngā hua o te ao tūturu e whiriwhiri i te kotahi tukanga anake. Ko te SMS-spunbond/meltblown/spunbond matarohia e whakakotahi ana i ngā mea pai o ngā mea e rua. Ka whakamahia e ngā kākahu hauora te spunbond o waho hei aukati i ngā wai, te meltblown o waenganui hei hopu i ngā matūriki, me te spunbond o roto hei whakamarie.kopare pokangaHe rite tonu: ka ārai te paparanga o waho i ngā tauhiuhi, ka hopu ngā huaketo i te mea i rewa, ā, ka mimiti te paparanga o roto i te makuku. Ahakoa he maha ngā tauera mākū e hono ana i te paparanga miro ngohengohe me te turanga miro pakari. He ngoikore ngā tukanga takitahi; ka puta te mahi pai i roto i ngā huinga mohio me te kore e pakaru te putea.
Kāore i te rite te hanga o ngā mea kore-whatu katoa
Kore-whatuKei ngā wāhi katoa - ngā kopare kanohi, ngā tauera horoi, ngā putea, ngā tātari, ngā kākahu - engari kāore te nuinga o te iwi e mōhio ki te wehewehe i waenga i te meltblown me te spunbond. Kua mōhio koe: me hiahia tātari? Me haere ki te meltblown. Me hiahia kaha, me te utu iti? Ko Spunbond tāu whakautu. Ā, ki te kite koe i te SMS, kei te titiro koe ki tētahi hanawiti i hangaia kia ātaahua. He ingoa "kakahu" kotahi, he tino rerekē te mahi - me te āputa utu e rima ngā whakarea. Mā te mārama ki ēnei huarahi e kore koe e mōhio ki te kakahu, engari ka mōhio ake koe ki te kaihoko.
