Imiba efuna ingqalelo kwi-PPSU kwiNkqubo yokuBunjwa kwesitofu

I-PPSU, igama lesayensi le-polyphenylene sulfone resin, i-amorphous thermoplastic ene-transparency ephezulu kunye nokuzinza kwe-hydrolytic, kwaye iimveliso zinokumelana nokuphindaphinda ukutshatyalaliswa kwentsholongwane.

I-PPSU ixhaphake kakhulu kune-polysulfone (PSU), i-polyethersulfone (PES) kunye ne-polyetherimide (PEI).

Ukusetyenziswa kwePPSU

1. Izixhobo zasekhaya kunye nezikhongozeli zokutya: zingasetyenziselwa ukwenza izixhobo ze-oven microwave, izifudumezi zekofu, izifudumezi, izixhobo zokomisa iinwele, izitya zokutya, iibhotile zabantwana, njl.

2. Iimveliso zeDijithali: endaweni yobhedu, i-zinc, i-aluminium kunye nezinye izinto zetsimbi, ukuveliswa kwamatyala okubukela, izinto zokuhombisa zangaphakathi kunye neefotokopi, iikhamera zekhamera kunye nezinye iindawo ezichanekileyo zesakhiwo.

3. Ishishini lomatshini: ubukhulu becala sebenzisa i-glass fibers eqiniswe iinkcukacha, iimveliso zineempawu zokuxhathisa i-creep, ukuqina, ukuzinza kwe-dimensional, njl., zilungele ukuveliswa kwezibiyeli zokuthwala kunye negobolondo leenxalenye zoomatshini njalo njalo.

4. Intsimi yezonyango kunye nempilo: ifaneleke kakhulu kumazinyo kunye nezixhobo zotyando, iibhokisi ze-disinfection (iipleyiti) kunye neentlobo zezixhobo zonyango ezingenakufakelwa ngabantu.

Ukubonakala kwePPSU

Amasuntswana endalo atyheli semi-transparent okanye amasuntswana opaque.

Iimfuno zokusebenza ngokwasemzimbeni zePPSU

Amanqaku amaninzi kufuneka athathelwe ingqalelo xa uyila iimveliso zePPSU kunye nokubumba

1. I-fluidity ye-PSU yokunyibilika ihluphekile, kwaye umlinganiselo wobude be-melt flow to wall ubukhulu bumalunga nama-80 kuphela. Ngoko ke, ubukhulu bodonga lweemveliso ze-PSU akufanele zibe ngaphantsi kwe-1.5mm, kwaye uninzi lwazo lungaphezu kwe-2mm.

Iimveliso ze-PSU zinobuntununtunu kwiinotshi, ngoko ke utshintsho lwe-arc kufuneka lusetyenziswe kwi-engile ekunene okanye ebukhali. Ukuncipha kokubumba kwe-PSU kuzinzile, okuyi-0.4% -0.8%, kwaye i-melt flow direction iyafana naleyo kwicala elithe nkqo. I-engile yokudiliza kufuneka ibe yi-50:1. Ukuze kufumaneke iimveliso eziqaqambileyo nezicocekileyo, uburhabaxa bomphezulu womgodi wokungunda bufuneka ukuba bube ngaphezu kweRa0.4. Ukuze kuququzelelwe ukunyibilika kokunyibilika, i-sprue ye-mold iyadingeka ukuba ibe mfutshane kwaye ibe nkulu, ububanzi bayo bube yi-1/2 yobunzima bemveliso, kwaye inethambeka le-3 ° ~ 5 °. Icandelo lomnqamlezo wesiteshi se-shunt kufuneka libe yi-arc okanye i-trapezoid ukuphepha ubukho be-bends.

2. Ifom yesango inokumiselwa yimveliso. Kodwa ubukhulu bufanele bube bukhulu ngokusemandleni, inxalenye echanekileyo yesango kufuneka ibe mfutshane ngokusemandleni, kwaye ubude bayo bunokulawulwa phakathi kwe-0.5 ~ 1.0mm. Indawo yezibuko lokutya kufuneka imiselwe kudonga olungqingqwa.

3. Misela imingxuma ebandayo eyaneleyo ekupheleni kwe-sprue. Kuba iimveliso ze-PSU, ngakumbi iimveliso ezinodonga olucekethekileyo, zifuna uxinzelelo oluphezulu lwenaliti kunye nesantya sokutofa ngokukhawuleza, imingxunya efanelekileyo yokukhupha okanye iigrooves kufuneka zisekwe ukuze kugqitywe umoya ekubumbeni kwangexesha. Ubunzulu bale mijelo okanye igrooves kufuneka bulawuleke ngaphantsi kwe-0.08mm.

4. Ukumiselwa kobushushu bokubumba kufuneka kube luncedo ekuphuculeni ukunyibilika kwe-PSU ngexesha lokuzaliswa kwefilimu. Iqondo lobushushu lokungunda linokuba phezulu njenge 140 ℃ (ubuncinci yi 120 ℃).
