30% girazi faibha yakasimbisa PA6 shanduko
30% girazi faibha yakasimbiswa PA6 yakagadziridzwa chip chinhu chakanakira kugadzirisa simba rekushandisa goko, masimba emidziyo yemagetsi, zvikamu zvemichina yekuvaka uye zvikamu zvemotokari. Iro mechanical properties, dimensional stability, kupisa kupisa uye kuchembera kuchembera kwakagadziridzwa zvakanyanya, uye simba rekuneta ndeye 2.5 nguva yeasina kukwidziridzwa, uye maitiro ekugadzirisa ndiwo anonyanya kuoneka.
Iyo jekiseni yekuumba maitiro e30% girazi fiber yakasimbiswa PA6 machipi akafanana neayo asina kusimbaradza, asi nekuti kuyerera kwakaipisisa kupfuura kuya kusati kwasimbiswa, kudzvanywa kwejekiseni uye kumhanya kwejekiseni kunofanirwa kuwedzerwa zvakakodzera. Maprocesspoints ndeaya anotevera:
1. Iyo tembiricha yebhari ye30% yegirazi fiber yakasimbiswa PA6 iri nyore kuwedzera ne10-40 ℃. Iyo tembiricha yedhiramu yakasarudzwa kuti iumbe jekiseni yePA6 yakagadziridzwa machipi ine hukama nehunhu hwemachipisi pachawo, zvishandiso uye chimiro chezvigadzirwa. Tembiricha yakakwira zvakanyanya zviri nyore kuita kuti zvikamu zveruvara zvishanduke, brittle, sirivheri waya uye humwe hurema, yakaderera dhiramu tembiricha iri nyore kuomesa zvinhu uye kukuvadza mold uye screw. Tembiricha yakanyungudika yakaderera yePA6 i220C. Nekuda kwekuyerera kwayo kwakanaka, naironi inoyerera nekuchimbidza kana tembiricha yadarika painonyungudika. Iyo fluidity ye30% yegirazi faibha yakasimbiswa PA6 yakagadziridzwa machipisi yakaderera zvakanyanya pane iyo yakachena zvinhu machipisi uye jekiseni giredhi PA6 machipisi, uye tembiricha yedhiramu iri nyore kuwedzera ne10-20 ℃.
2. 30% girazi fiber yakasimbiswa PA6 kugadzirisa mold tembiricha inodzorwa pa80-120C. Iyo tembiricha yekuumbwa ine imwe pesvedzero pane crystallinity uye molding shrinkage, uye huwandu hwekushisa kwe mold ndeye 80-120 ℃. Zvigadzirwa zvine hurefu hwemadziro akareba zvinofanirwa kusarudza tembiricha yakakwira mold, ine yakakwira crystallinity, yakanaka kupfeka kuramba, kuwedzera kuomarara uye elastic modulus, kuderera kwekunyura kwemvura uye kuwedzera kuumbwa kuderera. Zvigadzirwa zvakatetepa-madziro zvinofanirwa kusarudza yakaderera mold tembiricha, ine yakaderera crystallinity, yakanaka kuoma, kureba kwakakwira uye kuderera kuderera. Kana ukobvu hwemadziro hwakakura kupfuura 3mm, zvinokurudzirwa kushandisa yakaderera tembiricha mold pa20 ℃ kusvika 40 ℃. Iyo tembiricha yekuumbwa ye30% yegirazi yakasimbiswa zvinhu inofanira kunge yakakwira kupfuura 80 ℃.
3. Ukobvu hwemadziro e30% girazi fiber yakasimbiswa PA6 zvigadzirwa hazvifanirwe kunge zvisingasviki 0.8mm. Iyo yekuyerera kureba reshiyo yePA6 iri pakati pe150,200. madziro emadziro echigadzirwa haafanire kunge ari pasi peiyo 0.8mm. Kazhinji, sarudzo iri pakati pe1 ~ 3.2mm. Iyo shrinkage ye30% yegirazi fiber yakasimbiswa PA6 zvigadzirwa zvine hukama nekukora kwayo kwemadziro. Kuwanda kwemadziro emadziro, ndiko kukura kuderera.
4. Iyo exhaust orifice groove inofanira kudzorwa pazasi 0.025mm. Kufashukira kumucheto ukoshi hwe30% girazi faibha yakasimbiswa PA6 resin inenge 0.03mm, saka iyo yekubuditsa slot inofanirwa kudzorwa pazasi 0.025mm.
5. Gedhi regedhi harifaniri kunge riri pasi pe 0.5 kilott (t ndiyo hupamhi hwechikamu chepurasitiki). Negedhi rakanyura pasi, dhayamita shoma yegedhi inofanira kuva 0.75mm.
6. Iyo shrinkage ye30% yegirazi fiber yakasimbiswa PA6 zvigadzirwa zvinogona kuderedzwa kusvika 0.3%.
Iyo shrinkage yePA6 yakachena zvinhu iri pakati pe1% uye 1.5%, uye shrinkage inogona kuderedzwa kusvika inenge 0.3% mushure mekuwedzera 30% girazi fiber reinforcement. Chiitiko chinoshanda chinoratidza kuti iyo yakawanda girazi fiber inowedzerwa, idiki iyo yekuumba shrinkage yePA6 resin iri. Nekudaro, nekuwedzera kwehuwandu hwefiber, zvinokonzeresa pamusoro pefiber inoyangarara, kusawirirana kwakashata uye mimwe mhedzisiro, 30% girazi fiber reinforcement mhedzisiro yakanaka.
7. 30% girazi fiber yakasimbiswa PA6 yakadzokororwa zvinhu hazvifaniri kushandiswa kupfuura 3 nguva. 30% girazi faibha yakasimbiswa PA6 haina chero zvinhu zvakadzokororwa, asi kana vatengi vakashandisa yakawandisa zvinhu zvakadzokororwa, zviri nyore kukonzeresa kushanduka kwezvigadzirwa kana kuderera kwakanyanya mumakanika uye emuviri zvivakwa, huwandu hwekushandisa hunofanirwa kudzorwa pazasi 25%, zvikasadaro. zvinokonzeresa kushanduka kwemamiriro ekuita, uye kuomesa kurapwa kunofanirwa kuitwa zvisati zvashandiswazve zvinhu uye zvinhu zvitsva zvakasanganiswa.
8. Kuwanda kwekusunungura mumiririri idiki uye yunifomu. Iyo yekuburitsa mumiriri we30% girazi fiber yakasimbiswa PA6 zvigadzirwa zvinogona kusarudza zinc stearate uye chena mafuta, kana inogona kusanganiswa kuita paste, uye shoma shoma yekuburitsa mumiririri inogona kuvandudza uye kubvisa kuremara senge mabhuru. Kushandisa kunofanirwa kunge kuri kudiki uye kwakafanana, kuitira kuti kusakonzeresa kukanganisa kwepamusoro pezvigadzirwa.
9. Mushure mokunge chigadzirwa chacho chabuda mu mold, chiise mumvura inopisa kuti chitonhorere zvishoma nezvishoma. Nekuti iyo girazi faibha inotungamira munzira yekuyerera mune jekiseni rekuumba maitiro, iyo mechaniki zvivakwa uye shrinkage inosimudzirwa munzira yekutarisa, zvichikonzera deformation uye warping yezvigadzirwa. Nokudaro, mukugadzira mold, nzvimbo uye chimiro chegedhi chinofanira kuva chinonzwisisika. Kupisa kwemuumbi kunogona kusimudzwa mukugadzirisa, uye chigadzirwa chinofanira kuiswa mumvura inopisa kuti chitonhorere zvishoma nezvishoma.
10. 30% girazi faibha yakasimbiswa PA6 zvikamu zvinoshandiswa munzvimbo yakakwirira yekupisa inofanira kuve yakanyoroveswa. Nzira yekudzora humidity yekubikira mvura kana potassium diacetate solution inogona kushandiswa. Nzira yekudzora humidity yekuvira kwemvura inoisa chigadzirwa pahunyoro hwe65% kuti iwane kuenzana kwehunyoro. Tembiricha yekurapa ye potassium acetate aqueous solution (chiyero che potassium acetate kumvura 1.2515, boiling point 121C) is 80-100potassium acetate solution. Nguva yekurapa inonyanya kuenderana nechigadzirwa rusvingo ukobvu, apo madziro ukobvu anenge 2 maawa nokuda 1.5mm, anenge 8 maawa nokuda 3mm, uye anenge 16-18 maawa nokuda 6mm.
