Te Tuhura i nga Rawa me nga Hanganga o nga Kiriata Tiaki

Ko te kiriata whakamarumaru konumohe he tauira motuhake o te kiriata polyethylene (PE) hei tïpako, waikawa polyacrylic (ester) kapia hei rauemi tuatahi mo te whakapiri pehanga-tairongo, me te maha o nga taapiri taapiri motuhake na roto i te paninga, te tapahi, te kapi, me etahi atu tukanga, te Ko te kiriata whakamarumaru he ngohengohe, he pai te kaha o te whakapiri, he ngawari ki te whakapiri, he ngawari ki te tihorea. He pai te pumau o te whakapiri i te pehanga, kaore e pa ki te mata o te hua ka whakapiri.

Te whānuitanga o te tono: Te nuinga whakamahia mo nga momo katoa o te kirihou, rakau paraharaha (pepa) tiaki mata, pērā i PVC, PET, PC, PMMA rua-tae paraharaha, pahuka i te poari UV, karaihe, me te tahi atu papa pereti i roto i te waka, rokiroki , me te tukatuka, te tukanga whakauru kaore he kino.

Te hanganga me nga taonga o te kiriata whakamarumaru

Ko te kiriata whakamarumaru ko te kiriata whakamarumaru polyacrylate, te kiriata whakamarumaru polyacrylate o te hanganga taketake mai i runga ki raro: te paparanga wehe, te paparanga ta, te kiriata, te paparanga piri.

(1, apa wehe; 2, paparanga tā; 3, kiriata; 4, paparanga whakapiri)

1. Kiriata

Hei rauemi mata, he mea hanga te kiriata ki te polyethylene iti-kiato (PE) me te polyvinyl chloride (PVC). Ka taea te tango i te whakarewatanga, te werohanga, me te pupuhi pupuhi. I te mea he iti ake te utu o te polyethylene me te pai ake o te taiao, ko te 90% o te kiriata he mea hanga ki te polyethylene, ko te mahinga pupuhi te kaupapa matua. He maha nga momo polyethylene he rereke nga tohu whakarewa me te kiato.

2. Colloid

Ko nga ahuatanga o te colloid e whakatau ana i te matua ki te pai me te kino o te kiriata whakamarumaru. Ko te kiriata whakamarumaru e whakamahia ana i roto i te whakapiri pehanga-tairongo e rua nga momo: te whakapiri polyacrylate-whakarewa me te whakapiri polyacrylate wairewa-wai; he rereke nga ahuatanga.

Whakapiri polyacrylate-whakarewa

Ko te whakapiri polyacrylate e ahu mai ana i te whakarewa he whakarewa pararopi hei reo ki te whakakore i te monomer kiriaku; he tino marama te colloid, he iti te pokey tuatahi, he tino atete ki te koroheketanga mo te 10 tau ina pa ana ki te rama ultraviolet; ka ata rongoa hoki te colloid. Whai muri i te rongoa o te kiriata, ka taea te whakakikorua i te whakapiri polyacrylate me te kore he tuatahi. He uaua ake te whakapiri polyacrylate me te ngoikore o te wai, na reira ka puhoi ake te takaro o te whakapiri kiriata whakamarumaru; ahakoa i muri i te pehanga, karekau tonu e taea te whakapiri atu ki te kiri me te mata ka whakairihia. Whakanohoia 30 ~ 60 ra i muri mai, ka tino i roto i te whakapā ki te mata ki te whakairi kia rite ki te whakatutuki i te adhesion whakamutunga, me te adhesion whakamutunga ahu ki te kia nui atu i te adhesion o te adhesion o 2 ~ 3 wa, te adhesion o te kiriata whakamarumaru, mena e tika ana mo te tapahi wheketere o te poari, ka haehae te kaiwhakamahi mutunga i te kiriata i te wa kei reira He tino mahi, kaore ranei e taea te haea.

Whakapiri polyacrylate wai-wairewa

Ka whakamahia e te whakapiri polyacrylate te wai-wairewa te wai hei reo ki te memeha i te monomer kiriaku. Kei a ia ano nga ahuatanga o te piripiri polyacrylate e pa ana ki te whakarewa, engari me karohia te colloid hei whakaiti i te whakapiri ki te kohu wai me te aukati i te toenga o te kapia. He maha nga wa ka whakamahia e nga whenua whakawhanake te colloid ki te whakaputa kiriata whakamarumaru na te mea he pai ake te whakamaarama o te polyacrylate whakapiri wai-wairewa me te kore e hiahiatia he taputapu whakaora whakarewa.

3. Nga ahuatanga o te colloid

Whakapiri

E tohu ana ki te wa ka piri te kiriata whakamarumaru mai i te mata ki te kaha e hiahiatia ana mo te tihorea. Ko te kaha o te adhesion e pa ana ki nga mea e whakamahia ana, te pehanga, te wa tono, te koki, me te mahana i te wa e tihorea ana te kiriata. E ai ki a Coating Online, ko te tikanga, na te pikinga o te wa me te pehanga, ka piki ano te kaha piri; ka piki ake te piri o te kiriata whakamarumaru kia kore ai he toenga taapiri i te wa e haehae ana te kiriata.Ko te tikanga, ka tohua te whakapiringa ma te whakamatautau tihorenga 180-tohu.

Te whakakotahitanga

E tohu ana ki te kaha o te colloid i roto, i te mea me tino teitei te kiriata whakamarumaru o te whakakotahitanga colloid; ki te kore, i te haehae i te kiriata whakamarumaru, ka pakaru te colloid i roto, ka puta he toenga taapiri. Te inenga o te whakakotahitanga: Ka whakapirihia te kiriata whakamarumaru ki te mata kowiri tira, ka whakairihia he taumahatanga motuhake ki runga i te kiriata whakamarumaru hei ine i te roa o te wa e tangohia ai te kiriata whakamarumaru ma te taumaha. Mena he nui ake te kaha o te whakapiri i te kaha o te whakakotahitanga, haea te kiriata whakamarumaru, a ka pakaru nga ngota ngota piri e hono ana i waenga i te here, ka hua te toenga o te whakapiri.

Whakapiri

E pa ana tenei ki te kaha honohono i waenga i te whakapiri me te kiriata. Mena he nui ake te kaha o te whakapiri i te kaha o te whakakotahitanga, ki te tangohia te kiriata whakamarumaru, ka pakaru te here i waenga i nga ngota ngota piri me te kiriata, ka puta te toenga o te taapiri.

Atete UV

Ko te piripiri polyacrylate he atete UV, he kiriata whakamarumaru polyacrylate maramara me te whakapumau UV; he UV ātete hoki ki runga ki te 3 ~ 6 marama. Ko te whakamahi whanui o nga taputapu whaihanga huarere hei whakamatautau i te kaha o te UV o te kiriata whakamarumaru ma te whakatikatika i te kaha o te iraruke o te pāmahana, me te whakamaarama ki te whakatauira i te huringa o te rangi ia 3 haora o te haumākū nui me te 7 haora o te hihi ultraviolet mo te huringa o te 50 haora huringa o nga whakamatautau. e rite ana ki te rite mo te kotahi marama te whakanoho ki waho.
