Te kaupapa hanga o ngā rauemi whakamahana pahuka rehu
Ko te Whakamarumaru Huka Rehu (SPF) he rauemi whakamahana matatau i hangaia mā te whakahaere tika i te tauhohenga matū o ngā wāhanga wai matua e rua, te kapia polyol me te isocyanate. Ina konatunatua ēnei wāhanga e rua ki roto i tētahi taputapu rehu motuhake, ka puta he tauhohenga polymerization tere i raro i te mahi a tētahi whakakorikori, ā, ka tukuna te hau waro hauhā i te wā kotahi, ka whakawhanui te ranunga 30-60 ngā wā i roto i ētahi hēkona, ā, ka mutu ka hangaia he pahuka polyurethane me ngā āhuatanga whakamahana tino pai.
Ko te uho o tēnei tukanga matū ko te tauhohenga tāpiri polymerization o te isocyanate (-NCO) me te polyol (-OH), me te tauhohenga huka o te isocyanate me te wai hei whakaputa i te hauhā waro. Ko te taurite o ēnei tauhohenga whakataetae e rua e whakatau tika ana i te mahi whakamutunga o te pahuka, ā, koinei tonu te wāhi e whai wāhi nui ai ngā whakakorikori polyurethane.
He mahi tino pai oMXC-BDMAwhakakorikori
Ko tā mātou MXC-BDMA (N,N-dimethylbenzylamine, CAS 103-83-3) he whakakorikori amine tino whai hua kua arotauhia mō te pahuka mārō polyurethane, e whakaatu ana i ngā painga hangarau maha i roto i te hanga rauemi whakamahana pahuka rehu:
1. Te whakahaere tika i te tauhohenga
- E whakarato ana i te taurite tino pai o ngā tauhohenga huka/whakapūpū
- Ka whakarite kia pumau te pihi piki me te wā whakamaroke
- Ka urutau ki ngā āhuatanga pāmahana me te haumākū rerekē o te taiao
2. He kounga pahuka tino pai
- He hanganga pūtau-kati ōrite, he pai hoki (ōwehenga pūtau-kati >90%)
- Ka whakapai ake i te rere wawe o te pahuka, ā, ka whakarite kia tino whakakīia
- Ka whakarei ake i te kaha o te here i waenga i te pahuka me ngā momo papa
3. Ngā painga o te tukanga
-He pai mō ngā pūnaha whakatakotoranga totoka teitei
- Hototahi ki ngā momo pūwero pupuhi (HFC, HFO, wai, me ētahi atu)
- Ka whakaiti i ngā kakara amine noa, ka whakapai ake hoki i te taiao hangahanga
Kaiwhakaohorautaki kōwhiringa pūnaha
I te hanga pahuka rehu, me whai whakaaro ki ngā āhuatanga matua e whai ake nei i te kōwhiringa o ngā whakakorikori:
1. Ngā āhuatanga o te āhuarangi: te pānga o te pāmahana me te haumākū ki te tauhohenga
2. Ngā āhuatanga o te papa: ngā whakaritenga here mō ngā papa rerekē pēnei i te konganuku, te rakau, te raima, me ētahi atu.
3. Tukanga hanga: ngā rerekētanga i waenga i te rehu ā-ringa me te whakaputa tonu ā-mīhini
4. Ngā tohu mahi: ngā whakaritenga motuhake pēnei i te kawe wera, te porosity kati, me te whakatauranga ahi
Ka taea te whakamahi i te MXC-BDMA me ngā whakakorikori konganuku waro (pēnei i te stannous octoate) hei whakapai ake i te tere o te tauhohenga mā roto i ngā pānga honohono. Ko ngā otinga hangarau e taunakihia ana e mātou ko:
- Te whakamarumaru o te pakitara o waho o te whare: Ko te MXC-BDMA te pūnaha whakakorikori matua hei whakarite kia tere te whakamaroke
- Te whakamarumaru rokiroki matao: he pūnaha whakakorikori hiato hei whakapai ake i te tere pūtau-kati me te pumau o ngā āhuatanga
- Te whakamarumaru o ngā paipa ahumahi: he tauira motuhake hei urutau ki te hanganga mata piko matatini
Tautoko hangarau ngaio me ngā ratonga
