1, Cov khoom ntim
Nyob rau hauv xyoo tas los no, cov ntaub ntawv ntim khoom thiab cov khoom ntim tshiab tsim "kev hnav khaub ncaws" yog qhov tshwm sim. Cov ntawv ua haujlwm PP rau cov ntim ntau tshaj 50% sib dua li cov nplooj ntawv thiab feem ntau ntawm cov khoom siv sib xyaw ntawm cov ntawv. Hauv 1996, Tebchaws Asmeskas thermoformed PP daim npog ntawm cov khoom ntim zaub mov ntawm 143kt, Europe nyob hauv cov khoom ntim zaub mov, thermoformed PP foam daim ntawv qhia txog 10%. Plaub PP nrog ib qhov ceev ntawm 0. 5-0.7 g / cm3 thiab ib thickness ntawm 0.5 mus rau 1.5 hli yuav siv los ua khoom ntim (phaj, tais) nrog ib lub siab rigidity, haus ib khob; density ntawm 0.2 mus rau 1.5 g / cm3, Lub thickness ntawm 1.0 ~ 3.5 hli npaus PP ntawv yuav siv tau rau cov nqaij, zaub mov ntim khoom; Tsis tas li ntawd xwb, vim tias tus npaus dej PP muaj ib txoj kev zoo heev, yuav siv tau rau ntau lub computer, cov cuab yeej suab, cov koob yees duab, iav Ware thiab lwm yam khoom siv thiab hnav cov khoom ntim. Tib lub sijhawm
Npuas PP ntim siab tshaj li ntawm 130 ℃, thiab vim muaj qhov zoo siv microwave, nrog rau cov npauj npoo ntawv thermoformed thermoformed cov thawv ntim zaub mov siv tau rau hauv microwave; PP nws tus kheej, tus qauv ntawm PP ua kua cov khoom siv nrog kev ua kom zoo dua biodegradability, uas ua rau hauv ib lub lag luam ntim ua lag luam nyob hauv lub qhov tob ntawm tes, tshwj xeeb tshaj yog nyob rau hauv Suav vas nthiv kev lag luam, vim tsim cov tais diav ntim nrog cov npo Cov dej ua kom tsis muaj zog, tsis ua kom yooj yim dua, tsis muaj teeb meem, rov qab ua kom tsis zoo dua, tsis ua kom tawg, thiab ua lwm yam. tsis ntseeg ib qho kev xaiv uas zoo tshaj plaws.
2, Cov khoom siv hluav taws xob
PP ua npuas ncauj khoom cov khoom siv dag zog, kub kub thiab elongation ntawm so yog ho zoo tshaj PS npuas cov khoom, yuav siv tau raws li cov khoom siv hauv tsev, cov kav dej kub, cov khoom kub kub. Tam sim no, txawv teb chaws muaj ntau hom foaming PP rau npuas PS tshav kub tsis ua hauj lwm tsis tau raws li qhov yuav tsum muaj ntawm lub ntees, xws li 90 ~ 120 ℃ heat carrier lub roj teeb rwb thaiv tsev cov khoom, tsheb tav xis khoom, chav cav thiab rhiav Cov khoom kub , cov khoom ntim cushioning, thiab lwm yam, thiab tseem tuaj yeem hais tau tias nyob rau hauv tag nrho cov npuas PS, npuas PE khoom tshwm nyob rau hauv tshooj heat-resistant ntawm qhov chaw siv tau ua npuas ncauj.
3, Automotive sab hauv ntaub ntawv kho kom zoo nkauj
Ua luam dej nyob rau hauv xyoo tas los hauv kev lag luam automotive raws li kev txuas ntxiv ntawm daim ntawv thov ntawm cov ntaub ntawv zoo nkauj, uas ntxiv rau nws txoj kev nqus tau qhov muaj peev xwm siab, muaj peev xwm thiab kev kub hnyiab, rov ua dua kuj yog qhov tseem ceeb. Ua luam dej PP thiab PP, ABS thiab lwm yam ntaub ntawv hauv vaj hauv tsev thiab PVC, TPR thiab lwm cov ntaub ntawv ntim lossis thermal bonding, nqus moulding tuaj yeem ua tau tom qab qhov rooj, qab nthab thiab dashboard. Tib lub sijhawm
Thiab muaj peev xwm hloov tau cov khoom siv polyamide ua npuas ncauj, rau cov chav kawm ntawv qib siab, tsheb phab ntsa kho kom zoo nkauj thiab tsheb thawv thiab lwm yam. Qhov loj ntawm 0. 6 g / cm3, thickness ntawm 2 ~ 6mm npaus PP ntawv yuav ua tiav rau hauv cov ntaub pua plag kev pabcuam khoom, shading lub rooj tsavxwm, lub rooj tsav tsheb lub suab, lub qhovrooj qhov rooj, khib nyiab, tha xim sab hauv, lub thawv, raws li cov khoom ntub dej Thiab cov khoom siv insulating, piv txwv li, vim zoo creep tsis kam, tuaj yeem siv rau lub precision hluav taws xob Cheebtsam ntawm qhov huab. Tib lub sijhawm
Tsis tas li ntawd, PP ua npuas cov khoom tuaj yeem tau pom, xyaum, ntsia hlau thiab lwm yam kev ua haujlwm, tuaj yeem tsim ntxiv rau cov khoom siv hluav taws xob, cov ntaub ntawv kho kom zoo nkauj.
