muka kore-whatu rewa-pū
Ko te tikanga pupuhi-rewa tētahi o ngā tikanga polymer tika ki roto i te kupenga. Ko te tikanga whakaputanga tīwiri o te polymer rewa mā te pupuhi hau pāmahana teitei, mā tētahi atu tikanga rānei hei whakarewa i te maturuturunga o te taumahatanga nui, ka hangaia he muka tino pai, kātahi ka kohia ki roto i te kupenga roera, ki te kupenga rānei hei hanga i te whatunga muka, hei whakakaha i te pānga piri mai i te mea kua rewa te muka kore-whatu.
Te kaupapa hanga o te muka whakarewa-pūwero
1. Ngā āhuatanga ōrite me ngā rerekētanga ki te tikanga miro-hono
Tikanga here-miro
E mōhiotia ana hoki ko te tikanga miro tika ki te kakahu, ko te whakamahinga o ngā tikanga miro whakarewa pēnei i te wāhanga polymer mā te miro whakarewa me te totoro me te hanganga o te miro tonu mō te whatunga, kātahi ka honoa, ka whakaoti me ētahi atu tukanga hanga hua.
He mea noa
Me whakaputa te pūhui matūriki mā te kōhao hurihuri i te āhua rewa.
(2) ka taea e te whatunga muka te here wera (te here mata, te here pūwāhi rānei) te here rānei ki te whakakaha papanga kore-whatu
B te rerekētanga
I roto i te tikanga spunbond: ka whakamataohia te hau makariri ohorere, i te wa ano, ka totoro, ka hanga he miro tonu, ka horahia ki roto i te arai kupenga.
Tikanga rehu rewa: rehu hau wera tere teitei, mā te totoro tino, ka hangaia he muka poto tino pai, ka rere ki roto i te arai kupenga, ki te roera kupenga whakakorikori rānei i te tere tino tiketike hei hanga i te whatunga muka.
(2) tikanga spunbond: ngā tikanga whakapakari whatunga muka, hei tāpiri atu ki te hononga wera, engari ka whakamahia anō hoki te wero ngira, te wai, te hononga matū me ētahi atu tikanga
Tikanga rehu rewa: te nuinga o te wā ka whakawhirinaki ki te hononga wera, ki te hononga whaiaro rānei
2. Te tukanga hangarau tuku iho
Whāngai pūmua → whakaputanga rewa → hanganga muka → whakamatao muka → hanganga mata → hononga (mata pūmau) → takai mata tapahi → whakaotinga muri-whakaoti, whakaotinga motuhake rānei
Whāngai pūmua - ka hangaia te pūmua kia porowhita iti, kia kirikiri, ka ringihia ki roto i te peere, i te hopara rānei, ka whāngaihia ki roto i te mīhini whakaputa tīwiri.
Te whakarewa rewa -- i te pito whāngai o te mīhini whakarewa tīwiri, me whakaranu te poro pūmua ki te whakau, te kaihoko mā me ētahi atu tāpiringa, te rauemi tae matua me ētahi atu rauemi mata e tika ana, i muri i te whakaranu katoa ki roto i te mīhini whakarewa tīwiri, ka whakamahana kia rewa, ā, i te mutunga ka whāngaihia te rewa ki roto i te mīhini hurihuri e te papu ine mā te tātari. I roto i te tukanga whakarewa me te rehu, ka whakaitihia hoki e te mīhini whakarewa whānui te taumaha ngota o te pūmua mā tana mahi kutikuti me te whakahekenga wera.
Te hanganga muka - ka haere te rewa ma kua tātarihia mā roto i te pūnaha tohatoha, ā, ka whāngaihia kia ōrite ki roto i ia huinga o ngā miro hurihuri hei whakaputa i te nui o te whakaputanga mō ia miro hurihuri. He rerekē te miro hurihuri o te muka kua rehuhia ki te hanumi i ētahi atu tikanga miro, me whakarite ngā kōhao miro hurihuri kia rite ki te rārangi tika, he kōhao pupuhi kei ngā taha o runga me raro.
Te whakamatao muka - ka mimitihia he nui o te hau pāmahana rūma ki ngā taha e rua o te mīhini hurihuri, ka konatunatua ki te hau wera kei roto te muka-iti hei whakamatao. Ka whakamatao te muka-iti rewa, ā, ka totoka.
Kupenga - i roto i te hanga muka kore-whatu i pupuhihia e te hanumi, ka taea te whakanoho i ngā miro hurihuri ki te whakapae, ki te poutū rānei. Ki te whakanohohia ki te whakapae, ka rehuhia te muka moroiti ki runga i te pū kohi porowhita hei hanga kupenga. Ki te whakanohohia ki te poutū, ka taka ngā muka ki runga i te mata e neke ana ki te whakapae hei hanga kupenga.
Piripiri (whatunga pumau) - ko te whakakaha piri-ā-roto kua whakahuatia ake nei, mō ētahi take o te kakahu rehu rewa he nui, pēnei i: ngā whakaritenga o te whatunga muka he hanganga puhoi, he pai te pupuri hau, te ōwehenga koretake rānei. Ā, mō te maha atu o ngā whakamahinga, kāore e ranea te whakanui i te whakakorikori anake, me hiahia tonu te whakakorikori hurihuri wera, te whakakorikori ultrasonic, me ētahi atu tikanga whakanui rānei. Piripiri wera
3. Ngā āhuatanga tukatuka o te muka kore-whatu rewa-jet
(1) he poto te tukanga, he nui te whai huatanga o te whakaputa;
He tino angiangi te muka, he pai te ōrite o te mata o te muka, he ngawari, he tātari, he paturopi, he paitini hoki ngā painga o te mimiti.
Kāore i te pai te whakatakotoranga o te muka, he iti te kaha o te whatunga muka;
Ka nui te pūngao e pau i tēnei.
Ngā tawhā tukanga whakaputa matua o te tikanga rehu-rewa
1. Taupū rewa (MFI)
I heke te kaha me te roa o te papanga i rehuhia ki te hanumi i te pikinga ake o te MFI. Nō reira, me teitei te MFI o te rauemi mata kia pai ake ai te rere o te rewa angiangi i roto i te tukanga pupuhi hau wera.
2. Te tere o te rere o te hau wera
I raro i te pāmahana kotahi, te tere o te tīwiri, te tawhiti o te whiwhinga me ētahi atu tikanga:
Te tere o te hau wera ↑ → te whānui o te muka ↓ → te āhua o ngā mea kore-whatu mai i te pakeke ki te ngawari, ka piki ake ngā whiri o te muka, ka matotoru, ka maeneene te whatunga muka, ka piki ake te kaha
Engari he nui rawa te tere o te hau, he ngāwari ki te puta mai ngā putiputi rere, ā, ka pā kino ki te āhua o te kakahu.
3. Koki werohanga hau wera
Ka pā nui ki te pānga kume me te āhua o te muka
Ngā āhuatanga me te whakamahinga o te muka whakarewa-rere (te papanga kore-whatu)
1. Ngā rauemi tātari
Ko te nuinga o te wā ka whakamahia e ia tōna hanganga muka tino pai, koinei tōna mara tono tuatahi me te nui rawa atu. Ko te hiahia mō ngā rauemi tātari hou te tino kaha mō te whanaketanga o ngā muka kore-whatu rewa-pūhia.
Kāore he huruhuru poto o te rauemi tātari e taka ki roto i te hau, i te wai rānei kua parakore i muri i te tātaritanga ki te kakahu rehu rewa.
I tēnei wā, neke atu i te 20,000 tāne o ngā rauemi tātari rewa-jet e whakamahia ana i te ao i ia tau, 65% o ēnei e whakamahia ana mō te tātari wai, pērā i: te tātari inu me te horoi kai, te tātari wai, te tātari hangarua konganuku utu nui, te tātari peita me ngā paninga me ētahi atu hua matū; 35% e whakamahia ana mō te tātari hau, pērā i: te tātari hauhautanga o roto, te tātari wehenga hau me te wai, te tātari rūma purenga.
2. Ngā rauemi hauora
I tēnei wā, koinei te tuarua o ngā mara tono nui rawa atu mō te kakahu rehu-rewa.
I tēnei rohe, ko te horopeta nui rawa atu ko te takai pokanga, ngā ārai rūma pokanga me te kakahu takai patu huakita, me te iti o te takai rapa, te rīpene, me te kiriata whakamamae mumura.
3. Ngā rauemi parakore
(1) i roto i ngā tauera horoi
★ kakahu rehu rewa kua whakaurua ki roto i te matua mimiti o te tauera horoi, te paparanga whakawhiti capillary
★ te whakamahi i te kakahu rehu rewa hei ārai i te paparanga ārai urunga wai, me ngā paparanga e rua o te kakahu rehu rewa hei utu mō te kiriata ātete polyethylene
(2) mō ngā nāpi pakeke
I te tukanga whakaputa, ka konatunatua ngā muka poto o te penupenu rakau ki roto i te rere o ngā muka fusiform hei hanga i tētahi kakahu fusiform motuhake he pai te mimiti.
4. Ngā rauemi mimiti hinu
Hei rauemi mimiti hinu, ka taea e te kaha mimiti hinu te eke ki te 17 ngā wā o tōna ake taumaha.
Ko te tikanga, ka whakauruhia te kakahu rehu whakarewa ki roto i tētahi ngongo mata roa i whatuhia mai i te miro PET hei whatunga wai mānu hei ātete i te hinu me te mimiti hinu i te moana. Ka taea hoki te tāuta ki te pane o te waka tō moana i hangaia ki te kakahu rehu whakarewa PP hei taputapu kohikohi hinu, hei horoi tonu i te mata o te hinu.
5. Ngā rauemi kākahu
(1) ngā rauemi mahana
Ko te tono tino angitu ko te kakahu rehu-whakakotahi motuhake i whakawhanakehia e te kamupene 3M i te Hononga o Amerika: i roto i te tukanga o te muka rehu-whakakotahi, ka whakaranua te muka tōpū PET hei hanga i tētahi hanganga whakamarumaru hau i hangaia mai i te muka tōpū PET he pai te ngāwari me te muka PP tino pai.
(2) ngā kākahu mahi whakakorekore
Ko te whakamahinga matua o te kakahu hiato SMS, hei tāpiri atu ki te koti pokanga, kua angitu te whakamahi i roto i te whakamahinga ahumahi o ngā kākahu tiaki.
6, kakahu ma
Ko te nuinga o te whakamahinga ko te PP natural boil absorption, he momo momo e whakamahia ana mō te parahanga hinu o te taiao mahi.
I te whanaketanga o te hangarau tukatuka rewa me te rehu, ka taea te hanga i te kakahu rewa me te rehu PP me te āhuatanga hydrophilic mā te tāpiringa makuku tika, ka taea te whakamahi i roto i ngā hōhipera, i ngā rūma purenga teitei, i ngā wāhanga tino tika, i ngā taputapu me ngā rūma rorohiko.
