Cov teeb meem xav tau mloog ntawm PPSu hauv cov txheej txheem ntawm kev txhaj tshuaj molding

PPSU, lub npe scientific

PPSU yog qhov ntau tshaj polysulfone (PSU), Polyetherstulfone (PES) thiab polysheride (POLIN).

Daim ntawv thov ntawm PPSU

1. Cov khoom siv hauv tsev thiab khoom noj: tuaj yeem siv los tsim microwave cua sov, cov tshuab ntxhua khaub ncaws, cov khoom noj, cov menyuam fwj, thiab lwm yam, thiab lwm yam.

2. Cov khoom lag luam digital: hloov tooj liab, zinc, txhuas thiab lwm cov ntaub ntawv kho kom zoo nkauj thiab photocopers, cov koob yees duab thiab lwm yam precision cov txheej txheem.

3. Kev lag luam mechanical: Feem ntau siv iav fiber ntau txhawb cov kev txhawb nqa, nyuaj, haum rau cov kabmob nkhaus thiab cov tshuab tshuab zeb thiab lwm yam.

4. Kev kho mob thiab kev kho mob teb: Tsim nyog rau kev ntsuas hniav thiab phais, cov thawv tshuaj tua kab mob (cov hlau) thiab ntau ntawm tib neeg cov cuab yeej siv kev kho mob.

PPSU tsos

Ntuj daj daj pob zeb daj cua daj cua dub lossis opaque hais.

Kev ua yeeb yam ntawm lub cev uas xav tau ntawm Ppsu

Ob peb lub ntsiab lus yuav tsum tau them sai sai thaum tsim cov khoom ppsu thiab pwm

1. Lub fluidity ntawm psu yaj yog neeg pluag, thiab piv ntawm yaj flow cov khoom yuav tsum tsis pub tsawg tshaj 1.5mm, thiab feem ntau ntawm lawv yog saum toj kawg nkaus 2 hli.

Cov khoom siv PSU yog rhiab rau cov ntsiab lus tsis meej, yog li Arc hloov yuav tsum tau siv ntawm txoj cai lossis cov ces kaum. Cov voulding shrinkage ntawm PSU yog qhov ruaj ntseg, uas yog 0.4% -0.8%, thiab cov neeg npau npau ntws yog qhov zoo ib yam li uas nyob hauv cov kev taw qhia ntsug. Qhov demoulding lub ces yuav tsum yog 50: 1. Txhawm rau kom tau txais cov khoom ci thiab huv si, cov nplaim hluav taws xob ntawm cov pwm kab noj hniav yog qhov yuav tsum tau ua ntau dua RA0.4. Txhawm rau kom yooj yim rau cov lus yaj txaus, tus kab mob ntawm cov pwm yuav tsum tau luv thiab tuab, nws txoj kab ntawm cov khoom, thiab muaj ib txoj kab sib tw, thiab muaj kab nqes ntawm 3 ° ~ 5 °. Cov ntoo khaub lig nyob ntawm lub shunt channel yuav tsum arc lossis trapezoid kom zam dhau lub neej ntawm bends.

2. Cov qauv ntawm lub rooj vag tuaj yeem txiav txim siab los ntawm cov khoom lag luam. Tab sis qhov loj me yuav tsum muaj ntau li ntau tau, qhov ncaj nraim ntawm lub rooj vag yuav tsum yog luv li sai tau, thiab nws qhov ntev tuaj yeem tswj tau ntawm 0.5 ~ 1.0 hli. Txoj hauj lwm ntawm cov chaw nres nkoj pub mis yuav tsum tau teeb tsa ntawm phab ntsa tuab.

3. Teeb kom txaus txias qhov kawg ntawm sprue. Vim tias cov khoom lag luam psu, tshwj xeeb tshaj yog cov khoom lag luam uas muaj zog, xav tau kev txhaj tshuaj ntau dua, zoo nkauj yuav tsum teeb tsa cov pa tawm hauv cov pwm hauv lub sijhawm. Qhov tob ntawm cov vents lossis grooves yuav tsum tau tswj hwm hauv qab 0.08mm.

4. Qhov teeb tsa ntawm cov pwm kub yuav tsum tau txais txiaj ntsig zoo los txhim kho cov dej ntawm PSU melt thaum zaj duab xis puv. Cov pwm kub tuaj yeem ua kom siab npaum li 140 ℃ (tsawg kawg 120 ℃).
