Iindlela zokwenza ii-PPs: Inaliti, ukuphuma kwezinto, ukubumba, ukugxotha

Izinto ze-PPs kufuneka zomiswe kwi-oveni eyomileyo kangangeeyure ezingama-30 nge-150 ° C ngaphambi kokuqhubekeka. I-PPS engakhange yomiswe ngokupheleleyo ayiyi kuchaphazela i-homogeneity yenxalenye, kodwa inokubangela ingxaki ngexesha lokuqhutywa. Umzekelo, ukufuma okuqokelela kwi-filler yomxube kunokujika ibe yi-vapor kwaye wenze i-nozzles yomatshini obalekayo. Ke ngoko ukumiswa ngokuchanekileyo kwezinto ze-PPS ngaphambi kokuba kuqhubekeke. Izixhobo ezikhoyo zenziwe zisebenzisa iindlela ezahlukeneyo zokubumba, kubandakanya nenaliti yokubumba, ukubumba, kunye nokutshiza, kunye nokutshiza kunye nokutshiza kunye nokutshiza kunye nokutshiza kunye nokutshiza kunye nokubuyisa. Ezi ndlela zokulungisa zichazwe ngezantsi:

Inaliti yokubumba

Inaliti yokubumba yenye yeendlela eziqhelekileyo zokulungisa izinto zePPS. Xa intsingiselo yesifo, le nkqubo yenkqubo ilandelayo kufuneka iqatshelwe:

1. Iqondo lokushisa elifutshane: 280-30 ℃ yee-PPs ezinyulu, oqiniswe kwiBanga le-PPS nge-300-350 ℃.

2. Ubushushu be-nozzlelele: 305 ℃ kwi-PPS ecocekileyo, i-330 ℃ yokuqiniswa kwe-PPS.

3. Ubushushu obuMnyama: I-120-180 ℃.

4. Uxinzelelo lwenaliti: 50-130MPA.

Ukuphuma kwe-Exturis

I-Exturision ebumbayo yenye yeendlela eziqhelekileyo zokulungisa izinto zePPS. Ekuqaleni, kufuneka unikele ingqalelo kule nkqubo yenkqubo ilandelayo:

1. Iqondo lokushisa lecandelo lodondla: Ngaphantsi kwe-200 ℃.

2. Iqondo lobushushu elifutshane: 300-340 ℃.

3. Ubushushu bomzimba wokudibanisa: 320-340 ℃.

4. Iqondo lobushushu lomlomo: 300-30 ℃.

Ukubumba

Ukubuyisa kufanelekile kwiimveliso ezinkulu, ukusetyenziswa koxinzelelo ezimbini, ukupholisa okokuqala, ukucofa umlilo. Iqondo lobushushu lokuhambahamba limalunga ne-15min nge-360 ℃ yee-PP ezicocekileyo, kwaye malunga ne-20min nge-380 ℃ yokuqiniswa; Uxinzelelo lokubumba yi-10-30mpa, kwaye luphawulwe ukuya kwi-150 ℃ ukudilizwa.

Ukutshiza ukubumba

Ukutshiza ukubumba kukusetyenziswa kwezixhobo ze-Spray PPS ekutshintshelwe kumphezulu wensimbi, emva koko emva kokuqhwatywa, ukunciphisa unyango kwaye ufumane indlela yokuphindwayo. Xa ukutshiza, kufuneka unikele ingqalelo kule nkqubo yenkqubo ilandelayo:

1. Sebenzisa indlela yokumiswa kwe-streat kunye nokunqunyanyiswa kwe-sprain kunye ne-powder powder yendlela yokutshiza.

2. I-PPS itshizwe kumphezulu wensimbi. 3.

3. Ukuprinta kunye nokuzicingela kwenziwa ukuze ufumane ukuthuka.

4. Ukuphathwa gazi kwe-PPS kwenziwa kwiqondo lobushushu lama-300 ° C okanye ngaphezulu kwaye kwabanjwa kwimizuzu engama-30.
