Yog li, qhov txawv ntawm silicone roj hmab thiab TPE yog dab tsi? Silicone roj hmab yog ua los ntawm silicone, hluavtaws polymer. TPE yog ua los ntawm cov thermoplastic elastomers, uas yog kev sib xyaw ntawm cov yas thiab cov roj hmab.
Dab tsi yog qhov txawv ntawm silicone roj hmab thiab TPE?
Muaj ntau qhov sib txawv tseem ceeb ntawm silicone roj hmab thiab TPE. Silicone roj hmab yog cov roj hmab hluavtaws ua los ntawm silicone, thaum TPE yog thermoplastic elastomer. Silicone roj hmab muaj cov cua kub zoo thiab huab cua tsis kam, thaum TPE tsis. Silicone roj hmab kuj feem ntau kim dua TPE.
Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm silicone roj hmab?
Muaj ntau ntau yam khoom siv polymer muaj nyob rau hauv kev ua lag luam niaj hnub no, txhua tus muaj lawv tus kheej cov khoom tshwj xeeb thiab kev siv. Ob ntawm cov khoom siv nrov tshaj plaws siv hauv ntau qhov kev lag luam yog silicone roj hmab thiab thermoplastic elastomers (TPE). Txhawm rau txiav txim siab seb cov khoom twg yog qhov zoo tshaj plaws rau koj cov kev xav tau, nws yog ib qho tseem ceeb kom nkag siab qhov sib txawv tseem ceeb ntawm ob lub polymers.
Silicone roj hmab yog cov roj hmab hluavtaws inorganic tsim los ntawm silicone atoms thiab oxygen atoms. Cov khoom no paub txog nws qhov kev tiv thaiv rau huab cua kub, UV teeb, ozone, thiab oxygen. Tsis tas li ntawd, cov roj hmab silicone muaj kev tiv thaiv zoo rau dej thiab ya raws, ua rau nws zoo tagnrho rau kev siv hauv cov ntawv thov kev sib cuag nrog dej. Ib qho downside rau silicone roj hmab yog tias nws tuaj yeem raug nqi piv rau lwm cov polymers.
Thermoplastic elastomers (TPE) yog ib chav kawm ntawm cov ntaub ntawv copolymer uas nthuav tawm ob qho tib si thermoplastic thiab elastomeric zog. TPEs tuaj yeem ua pwm thiab zoo li cov thermoplastics, tab sis lawv muaj qhov elasticity ntawm cov roj hmab. Qhov no ua rau TPEs yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas yuav tsum tau ua kom yooj yim thiab ua haujlwm ntev. TPEs muaj nyob rau hauv ntau hom hardness, ua rau lawv haum rau txhua yam ntawm cov khoom ua si mos mus rau tawv-plhaub rooj plaub. Txawm li cas los xij, TPEs tuaj yeem nyuaj rau rov ua dua vim lawv qhov sib xyaw ua ke.
Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm TPE?
TPE yog ib chav kawm ntawm cov thermoplastic elastomers uas muaj cov roj hmab thiab cov khoom yas. TPE cov khoom muaj ntau yam zoo dua li cov khoom siv roj hmab. Lawv feem ntau muaj zog dua, nrog ntau dua tsim kua muag thiab abrasion tsis kam. Lawv kuj tiv taus cov roj feem ntau, tshuaj, UV lub teeb thiab kub hloov pauv zoo dua li roj hmab. TPEs yaj thiab ntws zoo li yas, yog li lawv tuaj yeem txhaj tshuaj molded lossis extruded nyob rau hauv qhov ntev ntev xws li roj hmab tubing. Thiab, zoo li roj hmab, TPEs tuaj yeem ua rau yuav luag txhua qhov kev xav tau.
Lub ntsiab tsis zoo ntawm TPEs yog lawv cov thermal stability piv rau lwm cov elastomers. Lawv tuaj yeem ua nkig ntawm qhov kub qis thiab tuaj yeem degrade ntawm qhov kub thiab txias. Qhov kub siab tshaj plaws no tuaj yeem ua rau cov khoom sib hloov lossis hloov pauv.
Thaum twg yog silicone roj hmab qhov kev xaiv zoo tshaj plaws?
Txawm hais tias ob qho tib si TPE thiab silicone roj hmab yog cov kev xaiv zoo rau ntau yam kev siv, muaj qee qhov xwm txheej uas silicone roj hmab yog qhov kev xaiv zoo dua.
Yog tias koj xav tau cov khoom siv uas tuaj yeem tiv taus qhov kub thiab txias, ces silicone roj hmab yog txoj hauv kev mus. Nws tuaj yeem tiv taus qhov kub txog li 400 degrees Celsius, ua rau nws zoo tagnrho rau cov ntawv thov uas qhov kub tsis kam yog qhov tseem ceeb.
Tsis tas li ntawd, silicone roj hmab muaj kev tiv thaiv zoo rau UV teeb thiab ozone, ua rau nws xaiv zoo rau kev siv sab nraum zoov. Thaum kawg, silicone roj hmab muaj cov khoom siv hluav taws xob zoo, ua rau nws zoo tagnrho rau siv hauv hluav taws xob Cheebtsam thiab cov khoom siv daim ntawv.
Thaum twg yog TPE qhov kev xaiv zoo tshaj?
TPE muaj ntau qhov zoo ntawm silicone roj hmab, suav nrog:
- Zoo dua tiv thaiv UV thiab ozonation
- Ntau dua elasticity thiab elasticity
- Kev puas tsuaj zoo dua
- Tus nqi qis dua
Txawm li cas los xij, tseem muaj qee qhov tsis zoo rau kev siv TPE, suav nrog:
-Poorer tsim kua muag zog
- Tsis zoo tiv thaiv kub kub
- Kev xaiv xim txwv
Yuav ua li cas xaiv ntawm silicone roj hmab thiab TPE?
Yog tias koj xav tau cov khoom siv ruaj khov, kub-resistant rau koj qhov project, tej zaum koj yuav xav paub seb puas siv silicone roj hmab los yog TPE (thermoplastic elastomer). Ob qho khoom siv muaj lawv qhov zoo thiab qhov tsis zoo, yog li nws tseem ceeb heev uas yuav tsum xaiv qhov tsim nyog rau koj cov kev xav tau.
