Ngā Pūrongo - He aha te utu nui o ngā papanga acetate

I ngā tau e rua kua pahure ake nei, he maha ngā kaihoahoa e kī ana "kakahu waikawa acetic" me "kakahu waikawa triacetic", kātahi ka huripokitia e rātou te tangi 3D, "kāore e taea te utu!" "Aue! Kāore e taea te whakamahi!" Ko tēnei momo papanga hoki te mea tino pai ki ngā kamupene waitohu teitei i ngā tau e rua kua pahure ake nei, kātahi kei hea?

Tohaina tonutia ngā momo taonga maroke katoa o te waikawa acetic, kei hea koe, ā, i a mātou e hoahoa ana i ngā kākahu, ka nui ake te utu o ngā papanga waikawa acetic? Whakamahia kia tika.

1. Waikawa aceticpapanga
Ko te muka acetate he momo muka horihori, he rauemi muka hanga-haurua, ka tauhohe te cellulose me te acetic anhydride ki te whiwhi muka acetate, kātahi ka mirohia te muka cellulose acetate ka hangaia. Ko te muka ACETATE, e mōhiotia ana ko te kakahu acetate, arā, he maha ngā tāngata e kī ana ko te kakahu waikawa acetic, e mōhiotia whānuitia ana ko te kakahu acetate, e mōhiotia ana ko Yasha, he kupu Hainamana mō te acetate Ingarihi.

Ka taea te wehewehe i te muka acetate ki ngā momo e rua, arā, te muka acetate me te muka acetate e toru. He aha te rerekētanga i waenga i te winika e rua me te winika e toru?

(1) He momo acetate te winika toru, kāore he waikura, ā, he teitei ake tōna taumata o te esterification. Nō reira, he kaha te ātete ki te mārama me te wera, he ngoikore te mahi tae, ā, he iti te tere mimiti makuku (e mōhiotia ana ko te tere whakahoki makuku).
(2) Ko te winika rua he momo acetate i hangaia i muri i te waikura wāhanga, ā, he iti iho tōna taumata o te esterification i tērā o te winika toru. Nō reira, kāore te mahi whakamahana i te pai pērā i te winika toru, he pai ake te mahi tae i te winika toru, ā, he teitei ake te tere mimiti makuku i te winika toru.

2. Kakahu waikawa triacetic
He maha ngā wā ka whakamahia te triacetate i roto i ā tātou hoahoa ahua. I ēnei rā, ka arotahi tātou ki te papanga triacetate nō te papanga waikawa acetic pai, nō reira, hei tāpiritanga ki te utu nui, te utu nui, te utu nui, te utu nui o te triacetate ~ he painga anō hoki mō te tinana katoa ~

Ko te Triacetate, i raro i te ingoa SOALON, i ahu mai i ngā rākau koniferi e whakatipuria ana i Kanata me Alaska. He muka parakore haurua-hangarau, i hangaia e te Kamupene Rayon Mitsubishi o Hapani, he momo hou o te huinga papanga taiao me te hangarau teitei, he rite te ngawari ki ngā muka taiao, engari he rite tonu tōna pānga ki ngā muka horihori.

I roto i te tukanga whakahāngai, ko te tohu whakahāngai he nui ake i te 2.7, ka kiia ko te muka triacetate, ā, ko te papanga i hangaia mai i te muka triacetate ka kiia ko te papanga triacetate.

3. PK me ngā muka taiao me ngā muka hanga-tangata

He rite te āhua me te kanapa o te muka triacetate ki te muka hiraka māpere. He rite anō te ngawari me te māeneene ki te muka hiraka māpere, ā, he rite tonu tōna taumaha ki te muka hiraka māpere, nō reira kāore he rerekētanga o te maroke me te muka hiraka māpere. Ko te āhuatanga ko te pikinga o te utu o ngā muka taiao i ngā tau tata nei, ā, kua pai te whakakapinga o te waikawa triacetic.

Nō reira, kāore he āhua rerekē o te hiraka me te kākahu. Ko te āhuatanga ko te pikinga o te utu o ngā muka taiao i ngā tau tata nei, ā, kua pai te whakakapinga o te waikawa triacetic.

Ngā tohu toa:
(1) He huakita, he puehu te papanga hiraka, ā, ka taea anake te horoi maroke, engari ehara i te mea ngāwari ki te whakaputa hiko pateko, ehara i te mea ngāwari ki te mimiti puehu i te rangi, ā, kāore he papanga hiraka e ngāwari ki te kai i ngā ngoikoretanga, he ngāwari ki te tiaki.
(2) He pai te āhua o te kakahu, he māmā ake te whakatika i te āhua, ki te whakaritea ki te rauemi hemp, kāore e ngāwari te mirimiri, he rite ki te rinena e mimiti ana i te makuku, engari he ahua ngoikore, he ahua makariri hoki i te wā e mau ana.
(3) He pai ake tēnei i ngā muka hangai nā te whakamarie o ngā muka tūturu. I taua wā anō, he pai ake te ngāwari o te muka viscose, engari he ngāwari hoki te tae, ā, he teitei ake te pumau o te tae.

4. Te tono me te tūnga o te papanga waikawa acetic i roto i te hoahoa kakahu

He nui te utu o te papanga waikawa acetic, ā, ka whakatauhia kia whakamahia ngā kākahu papai, me ētahi atu hiraka satin, kāore rānei e taea te whakakapi i te rauemi TR, e ai ki te whitiki utu waitohu, kia kitea ai mēnā he pai mō te waitohu.

(1) Te hoahoa ahua --kakahu

Kakahu waikawa acetic hei mahi i tekākahu paheke, ko te tikanga āke, ā, he maha ngā huarahi hei whakamārama i runga i te rerekētanga o te piko o te papanga, me te momo kakano o te papanga.

Waitohu: Ssheena
Ngā Kai: triacetate 82%, ethylene 18%)

(2) Hoahoa ahua -- tarau
He whakataukī tawhito rānei: ko te hoahoa tarau, kāore e taea te wehewehe i te whānui me te piko o te papanga. He rite tonu te rauemi waikawa acetic, kia aro ki te āhua satin o te waikawa acetic, ka mau hoki te āhua.
