I-Polyamide (PA) yipolymer equlethe amaqela aphindaphindiweyo e-amide kwikhonkco eliphambili.Idla ngokubizwa ngokuba yiNylon, iPA yenye yezona zinto ziphambili zaphuhliswa kwaye zisetyenziswa kakhulu iiplastiki zobunjineli.Kweli nqaku namhlanje,Qingdao Sainuoiya kukuthatha ukuba wazi amanqaku alishumi angundoqo okuguqulwa kwenayiloni.

pp waxyeNayiloni ilungisiwe

Iimpawu ezikhethekileyo zenayiloni zenza ukuba isetyenziswe ngokubanzi kwiimoto, izixhobo zombane kunye nombane, isakhiwo somatshini, izixhobo zemidlalo, iingubo kunye nokunye.Nangona kunjalo, ngokwenziwa kwemoto encinci, ukusebenza okuphezulu kwezixhobo zombane kunye nombane, kunye nokukhawuleziswa kwenkqubo yezixhobo ezikhaphukhaphu zoomatshini, imfuno yenayiloni kunye nokusebenza kwayo iyanda ngokuthe ngcembe.Ngoko ke ukuguqulwa kwenayiloni kubaluleke kakhulu.
Imiba efuna ukuqwalaselwa kuhlengahlengiso lwenayiloni
1. Ukusekwa kweqondo lobushushu lomphanda
(1) Ngenxa yokuba inayiloni iyipholima eyikristale, iqondo lokunyibilika kwayo liyabonakala.Ubushushu bombhobho we-nylon resin kwi-injection yokubumba ihambelana neempawu ze-resin, izixhobo kunye nokumila kwemveliso.

(3) Ngokubanzi, elona qondo lisezantsi lokunyibilika kwe-PA6 ngama-220 ℃ kunye ne-PA66 ngama-250 ℃.Ngenxa yokungazinzi kakuhle kwe-thermal ye-nylon, akufanelekile ukuhlala kwi-barrel ixesha elide kwiqondo lokushisa eliphezulu, ukuze kungabangela ukubola kunye nokuphuzi kwezinto.Kwangaxeshanye, ngenxa yobumanzi obuhle benayiloni, ibaleka ngokukhawuleza xa ubushushu budlula indawo yayo yokunyibilika.
2. Ukusetwa kobushushu bomngundo
(1) Iqondo lobushushu lokungunda linempembelelo ethile kwikristale kunye nokushwabana kokubumba.Ubushushu bomngundo buqala kwi-80 ℃ ukuya kwi-120 ℃.Ubushushu obuphezulu bokungunda, ubucwebe obuphezulu, ukwanda kokunganyangeki, ubulukhuni, imodyuli yokuqina, ukuncipha kokufunxwa kwamanzi, ukushwabana kokubumba okwandisiweyo, kukulungele imveliso eshinyeneyo;
(2) Ukuba ubukhulu bodonga bukhulu kune-3 mm, kuyacetyiswa ukuba usebenzise i-mold ephantsi yobushushu kunye ne-20 ~ 40 ℃.Kwizinto eziqiniswe ngeglasi, ubushushu bomngundo kufuneka bube ngaphezulu kwe 80 ℃.

3. Ubukhulu bodonga lweemveliso
Umlinganiselo wobude bokuhamba kwenylon yi-150-200, ubukhulu bodonga lwemveliso abukho ngaphantsi kwe-0.8mm, ngokubanzi i-1-3.2mm, kwaye ukucutha kwemveliso kuhambelana nobukhulu bodonga lwemveliso.Okukhona ukutyeba kodonga, kokukhona ukuncipha okukhulu.
4. Ukudinwa
Ixabiso lokuphuphuma kwentlaka yenayiloni malunga ne-0.03mm, ngoko ke umngxuma wokukhupha kufuneka ulawulwe ngaphantsi kwe-0.025.
5. Imbaleki kunye nesango
Ububanzi bomngxuma wesango akufunekanga bube ngaphantsi kwe-0.5T (t bubunzima benxalenye yeplastiki).Ngesango eliphantsi kwamanzi, ubuncinane besango lesango kufuneka libe yi-0.75mm.
6. Uluhlu lokuzaliswa kwefiber yeglasi
Kwinkqubo yokubumba inayiloni, ukunciphisa ubushushu bokubumba, ukwandisa uxinzelelo lwenaliti kunye nokunciphisa ubushushu bezinto eziphathekayo kuya kunciphisa ukushwabana kwenayiloni ukuya kuthi ga kwinqanaba elithile, ukonyusa uxinzelelo lwangaphakathi lwemveliso kwaye kwenze kube lula ukonakala.Ngokomzekelo, i-shrinkage ye-PA66 yi-1.5% ～ 2%, i-shrinkage ye-PA6 yi-1% ～ 1.5%, kwaye i-shrinkage ingancitshiswa ibe malunga ne-0.3% emva kokongeza i-glass fiber additive.
Amava asebenzayo asixelela ukuba okukhona ifayibha yeglasi isongezwa, kokukhona ukuncipha kokubumba kwentlaka yenayiloni.Nangona kunjalo, ukuba i-fiber yeglasi yongezwa kakhulu, iya kubangela i-fiber edadayo phezu komhlaba, ukungahambi kakuhle kunye nezinye iziphumo.Ngokuqhelekileyo, umphumo wokongeza i-30% ulungile.
7. Ukusetyenziswa kwezinto ezisetyenzisiweyo
Kungcono ukuba ungagqithisi amaxesha amathathu ukuphepha ukuguquguquka kwemveliso okanye ukuhla ngokukhawuleza kweempawu zomzimba kunye noomatshini.Isixa sesicelo kufuneka silawulwe ngaphantsi kwe-25%, kakhulu kuya kubangela ukuguquguquka kweemeko zenkqubo, kwaye umxube wezinto ezihlaziyiweyo kunye nezinto ezintsha kufuneka zomiswe.
8. Imiyalelo yokhuseleko
Xa i-nylon resin iqaliswa, ubushushu bombhobho kufuneka buvulwe kuqala, kwaye ubushushu kufuneka bufudunyezwe kwi-barrel yokutya.Xa umlomo uvaliwe, ungaze ujongane nomngxuma wokutshiza, ukuze uthintele ukukhululwa ngequbuliso kwenyibilika kumbhobho wokuxheshisela ngenxa yoxinzelelo lokuqokelelana, olunokubangela ingozi.

9. Ukusetyenziswa kwe-arhente yokukhululwa
Ukusetyenziswa kwenani elincinci le-ejenti yokukhupha isikhunta ngamanye amaxesha kunokuphucula kwaye kuphelise i-bubble kunye nezinye iziphene.I-arhente yokukhululwa kweemveliso ze-nylon ingaba yi-zinc stearate kunye neoli emhlophe, okanye ixutywe kwi-paste.Ubungakanani be-arhente yokukhulula kufuneka bube buncinci kwaye bufanane ukuze ugweme iziphene zomhlaba.Isikrufu kufuneka sicinywe xa umatshini uvaliwe ukuthintela isikrufu ekuqhekekeni ngexesha lemveliso elandelayo.

10. Emva konyango
(1) Iimveliso kufuneka ziphathwe ubushushu emva kokwenziwa
Iindlela eziqhelekileyo kwi-oyile yezimbiwa, i-glycerin, iparafini yolwelo kunye nolunye ulwelo oluphezulu lokubilisa, ubushushu bonyango lobushushu kufuneka lube ngu-10 ~ 20 ℃ ngaphezulu kobushushu bokusebenzisa, kwaye ixesha lonyango lixhomekeke kububanzi bodonga lwemveliso.Ubukhulu obungaphantsi kwe-3 mm yi-10 ~ 15 min, ubukhulu bu-3 ~ 6 mm, kwaye ixesha li-15 ~ 30 min.imveliso emva konyango lobushushu kufuneka ipholiswe kancinane kwiqondo lobushushu begumbi, ukuze kuthintelwe ukupholisa ngesiquphe ekubangeleni ukuveliswa kwakhona koxinzelelo kwimveliso.
(2) Iimveliso kufuneka ziphathwe ngolawulo lokufuma emva kokubumba
Ulawulo lokufuma lusetyenziswa ikakhulu kwiimveliso ezinomswakama ophezulu.Kukho iindlela ezimbini: enye kukubilisa ulawulo lokufuma kwamanzi;Enye inkqubo emanzi yesisombululo se-acetate ye-potassium yamanzi (umlinganiselo we-acetate ye-potassium kumanzi yi-1.25: 1, indawo yokubilisa i-121 ℃).
Amanzi abilayo alula, nje ukuba imveliso ibekwe kwindawo ye-65% yomswakama, ukwenzela ukuba ikwazi ukufikelela kwi-equilibrium ukufuma, kodwa ixesha lide.Ubushushu bonyango lwe-potassium acetate isisombululo esinamanzi yi-80 ~ 100 ℃, kwaye ixesha lonyango lixhomekeke ubukhulu becala kwimveliso yodonga, xa ubukhulu bodonga buyi-1.5mm, malunga ne-2h, 3mm, 8h, 6mm, 16 ~ 18h.
