I roto i te ao hurihuri o te whakamahana pahuka rehu, he wero nui tonu te whakatutuki i te hanganga pahuka ōrite me te pai o te whakamahinga wera. Kua hangaia e mātou te MXC-TMA Catalyst—he otinga hou kua hangaia hei huri i ngā tono pahuka polyurethane pakari. Ka tūhuratia e tēnei tuhinga te pēheaMXC-TMAe aro ana ki ngā mamae o te umanga me te whakarato i te mana whakahaere me te pumau e kore e taea te whakataurite.
He aha te take e hiahiatia ai he kaiwhakaoho tika mō te whakamahana pahuka rehu
Ko te whakamahana pahuka rehu he tūāpapa o te hanganga hou, e tuku ana i ngā uara-R pai rawa atu (tae atu ki te 7 ia inihi) me ngā āheinga hiri-hau. Heoi, ko ngā whakakorikori pāhare pāporo tuku iho ka arahi i te hanganga pūtau kore taurite, ngā rerekētanga kiato, me te nui rawa o ngā tukunga VOC—ngā take e whakararu ana i te mahi me te tutuki i ngā ture taiao whakakaha.
Ngā Wero Matua o te Ahumahi:
- Ngā pihi pikinga koretake i te wā e whakawhanui ana te pahuka
- He iti te rere o te wai i roto i ngā whakakīnga poka uaua
- Ngā taumata VOC neke atu i te 25 ppm (ka pā ki te kounga o te hau o roto)
- Te mimiti haere i muri i te tāutanga i ngā pāmahana tino kino
MXC-TMA Whakakōkī
Ko te MXC-TMA a MINGXU he whakakorikori o te whakatupuranga hou i hangaia mō te pahuka mārō polyisocyanurate (PIR). Hei wai kore tae ki te kōwhai-mā, ka whakakapia e ia ngā whakakorikori pāhare pāporo tawhito ki te mana whakahaere trimerization tika, e āhei ai ngā kaihanga ki te whakatutuki i:
1. Te Mana Tauhohenga Kāore i te ōrite
Ka whakau te MXC-TMA i te wāhanga whakatīmatatanga matua i te 55–75°C, kia rite ai te pikinga o te pihi me:
- Te Pūmautanga o te Wā Whakapūmau: ±3 hēkona (ki te ±8 hēkona mō ngā whakakorikori pāhare pāporo)
- Te ōritetanga o te mātotoru: <2% te rerekētanga o ia puranga
- Whakarei ake i te Taupū Rere: 92 CFI (18% teitei ake i ngā toharite o te ahumahi)
2. Te Rere Whakarei ake mō ngā Taupānga Uaua
Ka whakapai ake te hanganga ngota ngota o te whakakorikori i te wairewa o te pahuka, ka taea ai te whakakī maeneene i ngā kōhao uaua i roto i:
- Ārai Whare: Ka whakaiti i te para pahuka mā te 19% i roto i ngā āputa whaiti (0.5–1.5″)
- Ratonga Whakaterenga Mekameka Matao: Ka tutuki te kawe wera 0.023 W/m·K i roto i ngā taiao -40°C
- Paninga Paipa Ahumahi: Ka whakakore i ngā putunga hau i roto i ngā mata piko
Tangohia te Hipanga e Whai Ake nei ki te Pahuka Pai Ake
Tonoa tō Kete Tauira Koreutu i Tēnei Rā:
- 50 mL te rahi whakamātautau MXC-TMA
- Ngā MSDS me ngā tikanga whakamātautau e tutuki ana i te ASTM
- Ngā aratohu horopeta kua whakaritea mō tō tono
