Ko te hanga rongoā e hiahia ana kia tutuki ngā paerewa teitei o te whakahaere pāmahana, te pono o ngā tukanga, me te pono o te hua. Mai i te rokiroki rauemi mata ki te tohatoha hua kua oti, he mea nui te pupuri i ngā āhuatanga pāmahana tika hei whakatutuki i ngā whakaritenga GMP me te whakarite i te haumaru o te tūroro. Kei te ngākau o ia pūnaha mekameka makariri pono kei reira he hauhautanga tuarua whai hua - ā,Whakamatao Hukapapa LM-4e whakatakoto ana i te paerewa ahumahi.
He rerekē ki ngā pouaka whakamatao tuku iho e pirau haere ana i te roanga o te wā, ā, e whakararu ana i te mahi a te pūnaha, ka tukuna e te LM-4 te mahi wera ōrite me te tiaki i ngā taputapu mai i te waikura me te whakaroa i te roanga o te mahi.
Te Tūranga Hiranga o ngā Whakamatao Tuarua i roto i te Rongoā
Ko ngā pouaka whakamātao tuarua te reo kawe wera i roto i ngā pūnaha whakamātao rongoā, e whakawhiti ana i te wera i waenga i ngā taputapu tukatuka me ngā waeine pouaka whakamātao. Me taurite te pouaka whakamātao tuarua pai ki ngā whakaritenga maha:
- Whānuitanga Whakahaere:Tautoko i ngā pāmahana mai i te cryogenic (-80°C) ki te whakamahana tukatuka (150°C)
- Te Pūmautanga Matū:Ātete ki te pirau, me te pupuri i ngā āhuatanga i roto i te wā
- Hototahitanga Rauemi:Kāore e pirau, e kino rānei ngā wāhanga o te pūnaha
- Te Whai Hua o te Wera:Whakanuia te whakawhiti wera me te iti o te whakapaunga pūngao
- Haumaru:Kāore e mura, kāore e paitini, ā, he mea tiaki taiao
LM-4: Te Otinga Matatau mō ngā Whakamahinga Rongoā
Ka arohia ēnei whakaritenga e te Glacier Coolant LM-4 mā te whakamahi i tētahi whakatakotoranga motuhake e whakakotahi ana i ngā hangarau matua e toru:
1. Hangarau Ārai-Waikura M3 Ultra-Film
Mā tēnei hangarau auaha ka hangaia he paparanga ngota tiaki i runga i ngā mata whakarewa katoa, hei ārai i te waikura me te waikura. He rerekē ki ngā aukati tuku iho e memeha haere ana i roto i te wā, ka mau tonu te hangarau M3 i ōna āhuatanga tiaki puta noa i te roanga o te oranga o te wai.
2. Whakarerekētanga Whakakotahi Modify2000
Mā te whakarerekētanga matū matatau, ka tutuki i te LM-4 te pumau wera tino pai puta noa i tōna whānuitanga mahi katoa (-35°C ki te 150°C). Mā tēnei ka whakarite i te mahi ōrite i roto i ngā tono whakamatao me te whakamahana.
3. Pūnaha Whakamātautau Whānui a Box7
Ka whakamatautauria ia puranga LM-4 ki te mana kounga pakari, tae atu ki te chromatography hau-spectrometry papatipu, te tātari ira tio, te ine i te kawe wera, me te manatoko i te kaha wera motuhake.

Akoranga Take: Te Whare Hanga Pentaerythritol o te Rōpū Yuntianhua
Tirohanga Whānui o te Kaupapa:I whakahaerehia e te tipu hanga pentaerythritol a Yuntianhua Group tētahi pūnaha whakamatao ethylene glycol 200 m³ mō tāna tukanga whakaputa i te -10°C. I roto i ngā tau e rua o te whakatūnga, i pāngia te pūnaha e te waikura nui i tūpono ai te haere tonu o te whakaputanga.
Pānga Waikura:I hiahiatia kia neke atu i te 1 tana o te paru waikura te tango mai i te pūnaha mō ngā mahi tiaki ā-tau. Neke atu i te 455-838 mg/L te kukū o te katote rino i roto i te ethylene glycol, e tohu ana i te waikura kaha e angiangi ana i ngā pakitara o ngā paipa, e kino ana hoki ki ngā whakawhiti wera.
Te tahuritanga ki te LM-4:I whakakapia e te tipu te pūnaha ethylene glycol katoa ki te LM-4 Glacier Coolant. I uru atu ki te tukanga hurihanga te horoi i te pūnaha, te tango i te aukati waikura, me te whakakī LM-4 ki te kukū tino pai.
Te Aroturukitanga Mahi:I roto i ngā marama 17 o te mahi tonu, i whakaatuhia e ngā whakamātautau auau he pumau tonu ngā taumata katote rino i te 60-127 mg/L — he hekenga nui mai i te 455-838 mg/L o mua. I whakaatuhia e tēnei ngā kaha tiaki waikura pai rawa atu o LM-4.
Ngā Painga Matua i Tutuki:
- Te tango i te paru waikura i ia tau (1 tana+)
- Te whakaiti i te kukū o te katote rino mā te 85%
- Kua whakakorea ngā hapa taputapu e pā ana ki te waikura
- Ngā wā tiaki taputapu kua roa ake
Ngā Kōrero Angitu Anō
Kua puta ngā hua ōrite i te LM-4 puta noa i ngā whare hanga rongoā me ngā whare hanga matū:
Te Whare Hanga Pūmua Matūriki o Daqing
I waenga i te tau 2013 ki te 2018, i pāngia ngā pūnaha ethylene glycol me te tote e te angiangi haere o ngā pakitara paipa me ngā turuturu o te whakawhiti wera. Whai muri i te whakahoutanga ki te 35% LM-4, i whakakorea ngā hapa e pā ana ki te waikura, ā, i tau te mahi a te waeine whakamatao.
Zhejiang Chengda Pharmaceutical
I whakakapia te wai tote+mamao e te pūnaha whakawhiti pāmahana teitei-iti (-20°C ki te 120°C) ki te LM-4 hei reo kotahi, ā, ka taea te whakawhiti pāmahana aunoa me te whakapai ake i te pumau o te tukanga.
