Ngā kaihoko whakatauriteKo ngā mea e whakamahia ana i roto i ngā paninga ka whakarōpūtia whānuitia ki ngā whakarewa whakauru, te waikawa kiriaku, te silicone, ngā pūmua fluorocarbon me te cellulose acetate. Nā te iti o te mānukanuka o te mata, kāore e taea e ngā kaihoko whakataurite te āwhina i te paninga kia whakataurite noa, engari ka pāngia hoki e ngā pānga taha. I te wā e whakamahia ana, ko te whakaaro nui ko ngā pānga kino o ngā kaihoko whakataurite ki te kaha o te paninga ki te whakahou me ngā āhuatanga ārai-pupuhi o te paninga, ā, me whakamātautau te hototahitanga o ngā kaihoko whakataurite kua tīpakohia mā roto i ngā whakamātautau.

1. Kaiwhakarite whakarewa whakaranu

Ko te nuinga o te wā, he mea tito mai i ngā whakarewa hauwai kakara e koropupū ana, ngā ketone, ngā ester, ngā whakarewa pai rawa atu rānei o ngā rōpū mahi rerekē, me ngā ranunga whakarewa e koropupū ana. I te wā e whakarite ana, e whakamahi ana hoki, me aro ki tōna tere whakakorikori, te taurite whakakorikori me te wairewa, kia rite ai te tere whakakorikori me te wairewa o te paninga i te wā e whakamaroke ana. Ki te iti rawa te tere whakakorikori, ka roa te noho ki roto i te kiriata peita, ā, kāore e taea te tuku, ka pā ki te pakeke o te kiriata peita.

Ko tēnei momo kaitātai he mea tika anake mō te whakapai ake i ngā hapa tātai (pērā i te mimiti, te mā, me te kanapa ngoikore) i puta mai i te tere rawa o te maroke o te whakarewa paninga me te ngoikore o te wairewa o te rauemi turanga. Ko te horopeta he 2%~7% o te peita katoa. Ka roa ake te wā maroke o te paninga. Mō ngā paninga whakamaroke i te pāmahana rūma (pērā i te peita nitro) e ngawari ana te totohu ina pania ki te mata o mua, ehara i te mea ka āwhina noa i te tātai, engari ka āwhina hoki ki te whakapai ake i te kanapa. I te wā whakamaroke, ka taea hoki e ia te ārai i ngā mirumiru whakarewa me ngā kōhao iti i puta mai i te tere rawa o te mimiti o te whakarewa. Ina koa ka whakamahia i raro i ngā āhuatanga āhuarangi pāmahana teitei me te haumākū tiketike, ka taea e ia te ārai i te mata kiriata peita kei maroke wawe, ka whakarato i te pihi whakakorikori whakarewa ōrite, me te ārai i te puta o te kohu mā i roto i te peita nitro. Ko tēnei momo kaitātai ka whakamahia whānuitia me ētahi atu kaitātai.

2. Ngā kaihoko whakataurite kiriaku

Ko tēnei momo kaitātai he copolymer o ngā esters kiriaku. Ko ōna āhuatanga:

(1) Ko te alkyl ester o te waikawa kiriaku e whakarato ana i te mahi mata taketake;

(2) Tōna−COOH,−Ā, me−Ka taea e te NR te āwhina ki te whakarite i te hototahitanga o te hanganga alkyl ester;

(3) E pā tika ana te taumaha ngota ngota whanaunga ki te mahi horapa whakamutunga. Ko te hototahitanga nui me te whirihoranga mekameka o te polyacrylate he āhuatanga e tika ana kia noho hei kaihoko whakataurite tika. Ko tōna tikanga whakataurite ka kitea i te wāhanga o muri mai;

(4) He maha ngā pūnaha e whakaatu ana i ngā āhuatanga ārai-huka me te whakakore huka;

(5) I te mea he iti noa ngā rōpū hohe (pērā i te -OH, -COOH) i roto i te kaihoko whakataurite, kāore e kitea te pānga ki te paninga anō, engari kei te tūpono tonu te pānga ki te paninga anō;

(6) Kei reira anō te raruraru o te whakataurite i te polarity me te hototahitanga, e hiahia ana hoki ki te kōwhiringa whakamātautau.

3. Kaiwhakarite whakaōrite silicone

He momo pūmua ngā silicones me te mekameka here silicon-hāora (Si-O-Si) hei angaanga me ngā rōpū rauropi e piri ana ki ngā ngota silicon. Ko te nuinga o ngā matū silicone he mekameka taha me te iti o te kaha mata, nō reira he tino iti te kaha mata me te iti o te mānukanuka mata o ngā ngota silicone.

Ko te tāpiri polysiloxane e whakamahia whānuitia ana ko te polydimethylsiloxane, e mōhiotia ana ko te hinu methyl silicone. Ko tōna whakamahinga matua he tango i te pahuka. He pai ake ngā tauira taumaha ngota iti ki te whakatairanga i te whakataurite, engari nā ngā take hototahi nui, he maha ngā wā ka mimiti, ka kore rānei e taea te pani anō. Nō reira, me whakarerekē te polydimethylsiloxane i mua i te whakamahinga haumaru me te whai hua i roto i ngā paninga.

Ko ngā tikanga whakarerekētanga matua ko: te silicone whakarerekētia polyether, te silicone whakarerekētia alkyl me ētahi atu silicone whakarerekētia rōpū taha, te silicone whakarerekētia polyester, te silicone whakarerekētia polyacrylate, te silicone whakarerekētia fluorine. He maha ngā tikanga whakarerekētanga mō te polydimethylsiloxane, engari ko te whāinga katoa o ēnei he whakapai ake i tōna hototahitanga ki ngā paninga.

He maha ngā pānga o tēnei momo kaitārite ki te whakaōrite me te whakaiti i te huka. Me whakamātautau i mua i te whakamahinga mēnā ka hototahi ki te paninga.

4. Ngā kōrero matua mō te whakamahinga

Kōwhiria te momo tika: Kōwhiria te kaiwhakarite tika kia rite ki te momo me ngā whakaritenga mahi o te paninga. I te wā e whiriwhiri ana i tētahi kaiwhakarite, me whai whakaaro ki tōna hanganga me ōna āhuatanga me tōna hototahi ki te paninga tonu; i te wā kotahi, ka whakamahia ngā momo kaiwhakarite, ngā tāpiringa rānei hei whakataurite i ngā take maha.

Kia tūpato ki te nui o te mea e tāpirihia ana: mā te tāpiri nui rawa ka puta he raruraru pēnei i te mimiti me te totoro o te mata o te paninga, engari ko te iti rawa o te tāpiri e kore e tutuki te pānga whakataurite. I te nuinga o te wā, me whakatau te nui o te mea e tāpirihia ana i runga i te matotoru me ngā whakaritenga whakataurite o te paninga, me whai i ngā tohutohu mō te whakamahinga o te matū, ā, ka whakakotahi i ngā hua whakamātautau tuturu.

Tikanga paninga: Ka pāngia te mahi whakataurite o te paninga e te tikanga paninga. Ina whakamahia te kai whakataurite, ka taea e koe te whakamahi i te paraihe, te paninga roera, te rehu rānei hei whakatutuki i te mahi a te kai whakataurite.

Te whakaoho: I te whakamahinga o te kaiwhakarite, me whakaoho katoa te peita kia rite te horapa o te kaiwhakarite ki roto i te peita. Me whakatau te wā whakaoho kia rite ki ngā āhuatanga o te kaiwhakarite, kaua e neke atu i te 10 meneti.

He maha ngā momo rauemi e tukuna ana e Nanjing Reborn New Materialsngā kaihoko whakatauritetae atu ki ngā mea Organo Silicone me ngā mea Non-silicon mō te paninga. He rite te raupapa BYK.
