I. Whakahaere raina whakaputa.
① Aheamiihini karapu nitrile mo te hoko'S te pāmahana hinu kōhua ​​tae 190 ℃, te tere production ≤m ≤65pcs / min.
②I te mea he iti iho te pāmahana hinu kohua i te 145 ℃, me whakaheke te tere kia rite ki te tohu whakamaroke o te kiriata rapa.
③ ina he iti iho te pāmahana hinu kōhua ​​i te 130 ℃ me tango tonu kia mutu te mahi.
Tuarua, impregnating wairewa waikawa nitric: me whakahaere te kukū waikawa nitric i te 3%-4%, me whirihora i mua i te wairewa waikawa nitric ki te tank waikawa nitric me te kukū o te otinga, ka tino aukatihia te kaiwhakahaere ki te taapiri wai, waikawa nitric ki te tank i te hiahia.
Tuatoru, te whakamau i te wai kawakore: 5-10Kg o te kawakore ka taapirihia ki te tank alkali i ia nekehanga i te wa o te whakaputanga noa, me te 1 wa i muri i te 4 haora i te nekehanga e whai ake nei.
E wha, te parai i te pokepokea ringa: ① me whakahaere te pāmahana tank paraihe i te 45 ± 15 ℃
②Ko te wai horoi i pokepokea kia puhake, kia whakahoutia tonutia ki te kounga o te wai, me tino whakahouhia te kounga o te wai kotahi ia 8 haora.
③Me tirotirohia nga paraihe horoi mo nga makawe kia pai ai te mahi paraihe.
④Ko nga paraihe horoi i pokepokea kia pokea ki nga matū hinu.
E toru toua wai wera.
① me whakahaere te pāmahana tank wai wera i roto i te awhe o 80 ± 15 ℃, ka whakahouhia te kounga o te wai ki te pupuri i te ahua o te waipuke.Kia kotahi te wa whakakapia ia pokepokea horoi ringa waikawa.
E wha, te whakamau i te whakamaroke maaka.
① māngaro coagulant CaCL2 mana ihirangi i 8±3%.
②Makariki coagulant pāmahana whakaritenga 65±15 ℃.
③ Me tino whakakorikorihia te maaka kawa i ia 50-60 meneti.
③ te whakamaroke maaka ia 4-8 ra ki te whakahou kia kotahi te wa.
V. Te whakamaroke o te maaka: ① me whakamaroke te pokepokea mai i te oumu, engari he paku makuku te makuku o te ringa.
