30% galasi CHIKWANGWANI analimbitsa PA6 kusinthidwa
30% galasi CHIKWANGWANI analimbitsa PA6 kusinthidwa Chip ndi mfundo yabwino pokonza mphamvu chida chipolopolo, mbali zida mphamvu, mbali makina zomangamanga ndi mbali galimoto.Zochita zake zamakina, kukhazikika kwa mawonekedwe, kukana kutentha ndi kukana kukalamba zakhala zikuyenda bwino, ndipo mphamvu ya kutopa ndi nthawi 2.5 kuposa yosasinthika, ndipo zosintha zake ndizodziwikiratu.
Njira yopangira jakisoni ya 30% yamagalasi olimbitsa tchipisi a PA6 imakhala yofanana ndi yopanda kulimbikitsa, koma chifukwa kutuluka kwake kumakhala koyipa kuposa kulimbitsa, kuthamanga kwa jakisoni ndi liwiro la jakisoni ziyenera kukulitsidwa moyenera.Ma processing points ndi awa:
1. Kutentha kwa mbiya 30% galasi CHIKWANGWANI analimbitsa PA6 ndikosavuta kuonjezera 10-40 ℃.Kutentha kwa mbiya komwe kumasankhidwa kuti apange jakisoni wa tchipisi tosinthidwa za PA6 kumagwirizana ndi zomwe tchipisi tomwe, zida ndi mawonekedwe azinthuzo.Kutentha kwambiri zakuthupi n'kosavuta kupanga mbali kusintha mtundu, Chimaona, siliva waya ndi zolakwika zina, otsika kwambiri mbiya kutentha n'zosavuta kuumitsa zakuthupi ndi kuwononga nkhungu ndi wononga.Kutentha kotsika kwambiri kosungunuka kwa PA6 ndi 220C.Chifukwa cha madzi ake abwino, nayiloni imayenda mofulumira pamene kutentha kupitirira malo ake osungunuka.The fluidity wa 30% galasi CHIKWANGWANI analimbitsa PA6 kusinthidwa tchipisi ndi otsika kwambiri kuposa tchipisi koyera zinthu ndi jekeseni tchipisi PA6 tchipisi, ndi kutentha mbiya n'zosavuta kuonjezera ndi 10-20 ℃.
2. 30% galasi CHIKWANGWANI analimbitsa PA6 processing nkhungu kutentha umalamulidwa pa 80-120C.Kutentha kwa nkhungu kumakhudza kwambiri crystallinity ndi shrinkage, ndipo kutentha kwa nkhungu ndi 80-120 ℃.Zogulitsa zomwe zili ndi makulidwe apamwamba a khoma ziyenera kusankha kutentha kwakukulu kwa nkhungu, komwe kumakhala ndi crystallinity yapamwamba, kukana kuvala bwino, kuwonjezeka kwa kuuma ndi zotanuka modulus, kuchepetsa kuyamwa kwa madzi ndi kuwonjezeka kwa chrinkage.Zogulitsa zokhala ndi mipanda yopyapyala ziyenera kusankha kutentha kotsika kwa nkhungu, komwe kumakhala ndi crystallinity yochepa, kulimba bwino, kutalika kwambiri komanso kuchepa kwapang'onopang'ono.Ngati makulidwe a khoma ndi wamkulu kuposa 3mm, tikulimbikitsidwa kugwiritsa ntchito nkhungu yotsika kutentha pa 20 ℃ mpaka 40 ℃.Kutentha kwa nkhungu kwa 30% zolimbitsa magalasi kuyenera kukhala kwakukulu kuposa 80 ℃.
3. makulidwe a khoma la 30% galasi CHIKWANGWANI analimbitsa PA6 mankhwala sayenera kuchepera 0.8mm.Kutalika kwakuyenda kwa PA6 kuli pakati pa 150,200.makulidwe a khoma la mankhwala sikuyenera kukhala otsika kuposa 0.8mm.Nthawi zambiri, kusankha kuli pakati pa 1 ~ 3.2mm.Kuchepa kwa 30% ya zinthu zamagalasi zolimbikitsidwa za PA6 zimagwirizana ndi makulidwe ake.Kukhuthala kwa khoma kumachulukira, kumacheperachepera.
4. The exhaust orifice groove iyenera kuyendetsedwa pansi pa 0.025mm.Kusefukira kwa m'mphepete mwa 30% magalasi opangidwa ndi utomoni wa PA6 ndi pafupifupi 0.03mm, kotero kagawo kotulutsa mpweya kuyenera kuyendetsedwa pansi pa 0.025mm.
5. Kutalika kwa chipata sikuyenera kuchepera 0.5 kilott (t ndi makulidwe a gawo la pulasitiki).Ndi chipata chomira pansi, m'mimba mwake osachepera 0.75mm.
6. The shrinkage wa 30% galasi CHIKWANGWANI analimbitsa mankhwala PA6 akhoza kuchepetsedwa kukhala 0.3%.
Kuchepa kwa zinthu zoyera za PA6 kuli pakati pa 1% ndi 1.5%, ndipo kucheperako kumatha kuchepetsedwa mpaka 0.3% mutawonjezera 30% kulimbitsa magalasi.Zochitika zowoneka bwino zikuwonetsa kuti ulusi wagalasi ukawonjezedwa, m'pamenenso utomoni wa PA6 umakhala wocheperako.Komabe, pakuwonjezeka kwa kuchuluka kwa ulusi, kumayambitsanso ulusi woyandama, kusalumikizana bwino ndi zotsatira zina, 30% yolimbitsa magalasi yamagalasi ndi yabwino.
7. 30% galasi CHIKWANGWANI analimbitsa PA6 zobwezerezedwanso zipangizo sayenera kugwiritsidwa ntchito kuposa 3 zina.30% galasi CHIKWANGWANI analimbitsa PA6 lilibe zipangizo zobwezerezedwanso, koma ngati makasitomala ntchito kwambiri zobwezerezedwanso zipangizo, n'zosavuta chifukwa kusinthika kwa zinthu kapena kutsika kwambiri mawotchi ndi thupi katundu, kuchuluka ntchito ayenera kulamulidwa pansipa 25%, apo ayi. zidzayambitsa kusinthasintha kwa zochitika za ndondomeko, ndipo kuyanika mankhwala kuyenera kuchitidwa pamaso pa zipangizo zobwezerezedwanso ndi zipangizo zatsopano zosakanizidwa.
8. Kuchuluka kwa nkhungu yotulutsa wothandizira ndi yaying'ono komanso yofanana.Wotulutsa wa 30% galasi CHIKWANGWANI analimbitsa PA6 mankhwala akhoza kusankha zinc stearate ndi mafuta woyera, kapena akhoza kusakaniza phala, ndi pang'ono kumasulidwa wothandizila akhoza kusintha ndi kuthetsa zilema monga thovu.Kugwiritsa ntchito kuyenera kukhala kocheperako komanso kofanana, kuti zisapangitse kuwonongeka kwa zinthu.
9. Mankhwalawa akatuluka mu nkhungu, yikani m'madzi otentha kuti muzizizira pang'onopang'ono.Chifukwa ulusi wagalasi umayang'ana njira yolowera munjira yopangira jakisoni, zida zamakina ndi kucheperako zimakulitsidwa momwe zimayendera, zomwe zimapangitsa kuti zinthu zisinthe komanso ziwonjezeke.Choncho, mu mapangidwe a nkhungu, malo ndi mawonekedwe a chipata ayenera kukhala omveka.Kutentha kwa nkhungu kumatha kukwezedwa panthawiyi, ndipo mankhwalawa ayenera kuikidwa m'madzi otentha kuti azizizira pang'onopang'ono.
10. 30% galasi CHIKWANGWANI analimbitsa PA6 mbali ntchito mu kutentha chilengedwe ayenera moisturized.Njira yowongolera chinyezi yamadzi otentha kapena potassium diacetate solution ingagwiritsidwe ntchito.Njira yowongolera chinyezi yamadzi otentha imayika mankhwalawa pa chinyezi cha 65% kuti azitha kuyamwa bwino chinyezi.Kutentha kwa mankhwala a potaziyamu acetate amadzimadzi (chiŵerengero cha potaziyamu acetate ndi madzi ndi 1.2515, kutentha kwa 121C) ndi 80-100potassium acetate solution.The mankhwala nthawi makamaka zimadalira mankhwala khoma makulidwe, pamene khoma makulidwe pafupifupi 2 hours kwa 1.5mm, za 8 hours 3mm, ndi za 16-18 maola 6mm.
