IiNqaku ezili-10 eziPhambili zokuCwangciswa kunye nokuBunjwa kwe-PA6 + 30% yeGlassfiber eQinisekisiweyo

I-30% ifayibha yeglasi eqiniswe ukulungiswa kwePA6

I-30% ifayibha yeglasi eyomeleziweyo ye-PA6 eguqulweyo yetshiphu yinto efanelekileyo yokusetyenzwa kwesixhobo samandla eqokobhe, iinxalenye zesixhobo samandla, iinxalenye zoomatshini bokwakha kunye neenxalenye zemoto. Iimpawu zayo zomatshini, ukuzinza kwe-dimensional, ukumelana nobushushu kunye nokuchasana nokuguga kuye kwaphuculwa kakhulu, kwaye amandla okudinwa ngama-2.5 amaxesha angaphuculwanga, kwaye umphumo wokuguqulwa ngowona ucacileyo.

Inkqubo yokubumba i-30% yeglasi yefayibha eyomeleziweyo ye-PA6 chips iphantse yafana naleyo ngaphandle kokuqiniswa, kodwa ngenxa yokuba ukuhamba kubi kakhulu kunoko ngaphambi kokuqiniswa, uxinzelelo lwenaliti kunye nesantya sokutofa kufuneka sonyuswe ngokufanelekileyo. Iindawo zokusetyenzwa zimi ngolu hlobo lulandelayo:

1. Ubushushu bomgqomo we-30% ifayibha yeglasi eyomeleziweyo i-PA6 kulula ukunyuka nge-10-40 ℃. Ubushushu bomgqomo okhethiweyo wokubumba inaliti yeetshiphusi eziguquliweyo zePA6 zihambelana neempawu zeetshiphusi ngokwazo, izixhobo kunye nemiba yeemveliso. Ubushushu bezinto eziphakamileyo kakhulu kulula ukwenza iinxalenye zokutshintsha kombala, i-brittle, i-wire yesilivere kunye nezinye iziphene, iqondo lokushisa eliphantsi kakhulu lomphanda kulula ukwenza lukhuni izinto kunye nokonakalisa isikhunta kunye nesijija. Elona qondo lisezantsi lokunyibilika kwe-PA6 yi-220C. Ngenxa yobumanzi bayo obulungileyo, inayiloni ibaleka ngokukhawuleza xa ubushushu bugqitha kwindawo yayo yokunyibilika. I-fluidity ye-30% ifayibha yeglasi eyomeleziweyo ye-PA6 chips eziguquliweyo isezantsi kakhulu kunoko kweetshiphusi zezinto ezinyulu kunye neetshiphusi zebanga lokutofa i-PA6, kwaye iqondo lobushushu lomgqomo kulula ukunyuka nge-10-20 ℃.

2. I-30% ifayibha yeglasi eyomeleziweyo i-PA6 yobushushu bokucwangcisa i-mold ilawulwa kwi-80-120C. Iqondo lobushushu lokungunda linempembelelo ethile kwikristale kunye nokuncipha kokubumba, kwaye uluhlu lobushushu lokungunda luyi-80-120 ℃. Iimveliso ezinobunzima obuphezulu bodonga kufuneka zikhethe ubushushu obuphezulu bokubumba, obunobukristale obuphezulu, ukumelana nokunxiba kakuhle, ukonyuka kokuqina kunye ne-elastic modulus, ukuncipha kokufunxa kwamanzi kunye nokunyuka kokubumba. Iimveliso ezinodonga olubhityileyo kufuneka zikhethe ubushushu obuphantsi bokungunda, obunobucwebe obuphantsi, ukuqina okuhle, ubude obuphezulu kunye nokuncipha kokuncipha. Ukuba ubukhulu bodonga bungaphezulu kwe-3mm, kuyacetyiswa ukuba usebenzise isikhunta sobushushu obuphantsi kwi-20 ℃ ukuya kwi-40 ℃. Ubushushu bomngundo obuyi-30% yeglasi eyomeleziweyo kufuneka bube ngaphezulu kwe 80 ℃.

3. Ubukhulu bodonga lwe-30% yeglasi ifayibha eqinisiweyo iimveliso ze-PA6 akufanele zibe ngaphantsi kwe-0.8mm. Umlinganiselo wobude bokuhamba kwe-PA6 uphakathi kwe-150,200. ubukhulu bodonga lwemveliso akufanele bube ngaphantsi kwe-0.8mm. Ngokubanzi, ukhetho luphakathi kwe-1 ~ 3.2mm. Ukucutheka kwe-30% yeemveliso zeglasi zefayibha ezongeziweyo ze-PA6 kuhambelana nobukhulu bodonga lwayo. Okukhona ukuqina kodonga, kokukhona ukuncipha.

4. I-exhaust orifice groove kufuneka ilawulwe ngaphantsi kwe-0.025mm. Ixabiso lomphetho ophuphumayo we-30% yeglasi yefayibha eqiniswe i-PA6 resin imalunga ne-0.03mm, ngoko ke i-exhaust slot kufuneka ilawulwe ngaphantsi kwe-0.025mm.

5. Ubukhulu besango akufanele bube ngaphantsi kwe-0.5 kilott (t bubunzima benxalenye yeplastiki). Ngesango eliphantsi kwamanzi, ubuncinci bobubanzi besango kufuneka bube yi-0.75mm.

6. I-shrinkage ye-30% ye-glass fiber eqiniswe iimveliso ze-PA6 zingancitshiswa zibe yi-0.3%.

I-shrinkage yezinto ezicocekileyo ze-PA6 ziphakathi kwe-1% kunye ne-1.5%, kwaye i-shrinkage ingancitshiswa ibe malunga ne-0.3% emva kokongeza i-30% ye-glass fiber reinforcement. Amava asebenzayo abonisa ukuba okukhona ifayibha yeglasi isongezwa, kokukhona kucutheka kokubumba kwe-PA6 resin. Nangona kunjalo, ngokunyuka komyinge wefayibha, kuya kubangela ifayibha edadayo kumphezulu, ukungahambelani kakuhle kunye nezinye iziphumo, i-30% yeglasi yeglasi yokuqinisa isiphumo ilungile.

7. I-30% ye-glass fiber eqiniswe izinto ezihlaziyiweyo ze-PA6 akufanele zisetyenziswe ngaphezu kwamaxesha e-3. I-30% i-fiber yeglasi eyomeleziweyo ye-PA6 ayinayo nayiphi na into esetyenzisiweyo, kodwa ukuba abathengi basebenzisa izinto ezininzi ezisetyenzisiweyo, kulula ukubangela ukubola kweemveliso okanye ukuhla okubukhali kwiipropati zoomatshini nezomzimba, ixabiso lesicelo kufuneka lilawulwe ngaphantsi kwe-25%, ngaphandle koko. iya kubangela ukuguquguquka kweemeko zenkqubo, kwaye ukomisa unyango kufuneka lwenziwe ngaphambi kokuba izinto ezihlaziyiweyo kunye nezinto ezintsha zixutywe.

8. Ubungakanani be-ejenti yokukhulula i-mold incinci kwaye ifanayo. I-arhente yokukhululwa ye-30% ye-glass fiber eqiniswe imveliso ye-PA6 inokukhetha i-zinc stearate kunye neoli emhlophe, okanye inokuxutywa kwi-paste, kwaye i-agent encinci yokukhululwa inokuphucula kunye nokuphelisa iziphene ezifana namaqamza. Ukusetyenziswa kufuneka kube kuncinci kwaye kufane, ukuze kungabangela iziphene ezingaphezulu kweemveliso.

9. Emva kokuba imveliso iphumile kwi-mold, yibeke emanzini ashushu ukupholisa ngokukhawuleza. Ngenxa yokuba i-fiber yeglasi iya kuhamba ecaleni kwendlela yokuhamba kwinkqubo yokubumba, iipropathi zoomatshini kunye nokuncipha kuya kuphuculwa kwicala lokuqhelaniswa, okukhokelela kuguquko kunye nokulwa kweemveliso. Ngoko ke, kuyilo lokubumba, isikhundla kunye nokuma kwesango kufuneka kube nengqiqo. Iqondo lokushisa lokubumba linokunyuswa kwinkqubo, kwaye imveliso kufuneka ifakwe emanzini ashushu ukupholisa ngokukhawuleza.

10. I-30% ifayibha yeglasi eyomeleziweyo iindawo zePA6 ezisetyenziswa kwindawo yobushushu obuphezulu kufuneka zifume. Indlela yokulawula ukufuma kwamanzi abilayo okanye isisombululo se-potassium diacetate singasetyenziswa. Indlela yokulawula ukufuma kwamanzi abilayo ibeka imveliso kubumanzi obungama-65% ukufezekisa ukufunxwa kokufuma okulinganayo. Ukushisa kwonyango lwe-potassium acetate isisombululo samanzi (umlinganiselo we-potassium acetate kumanzi ngu-1.2515, indawo yokubilisa i-121C) yi-80-100potassium acetate isisombululo. Ixesha lonyango ikakhulu lixhomekeke kubukhulu bodonga lwemveliso, xa ubukhulu bodonga bumalunga neeyure ezi-2 kwi-1.5mm, malunga neeyure ezi-8 ze-3mm, kunye neeyure ezingama-16-18 ze-6mm.
