Tau ntim rau hauv woven los yog hemp hnab lined nrog hnab yas, txhua lub hnab muaj ib tug luj ntawm 25kg, 40kg, 50kg los yog 500kg.Khaws rau hauv qhov chaw txias thiab qhov cua, hluav taws kub thiab noo noo.Tsis txhob sib tov nrog kua qaub thiab alkali.Raws li cov kev cai ntawm flammable cia thiab tsheb thauj mus los.
Taw qhia
Taw qhia Sebacic Acid - ntau yam, dawb patchy siv lead ua uas tau nce siab hauv kev muaj koob meej ntau xyoo, ua tsaug rau nws cov kev siv ntau yam hauv ntau qhov kev lag luam.Sebacic acid yog dicarboxylic acid nrog cov tshuaj formula HOOC (CH2) 8COOH thiab soluble hauv dej, cawv, thiab ether.Cov organic acid no feem ntau tau txais los ntawm cov noob ntawm cov nroj tsuag roj castor, thiab nws yog ib qho tseem ceeb raw cov ntaub ntawv siv hauv kev lag luam tshuaj.
Sebacic acid feem ntau yog siv los ua cov khoom siv raw rau sebacate plasticizer thiab nylon molding resin.Qhov no yog vim nws lub peev xwm los txhim kho qhov elasticity thiab yooj ntawm ntau yam polymers yam tsis muaj kev cuam tshuam lawv cov kev ua tau zoo lossis kev ruaj ntseg.Nws txhim khu kev tiv thaiv rau huab cua kub, txiav, thiab punctures nrog rau kev txhim kho tensile thiab compressive zog ntawm cov ntaub ntawv nylon.Yog li ntawd, nws tau txais kev lees paub dav hauv kev lag luam yas.
Sebacic acid kuj tseem siv ntau heev hauv kev tsim cov roj uas muaj kub-resistant lubricating roj.Vim nws compatibility nrog high-temperature ib puag ncig, nws ua hauj lwm raws li ib tug zoo lub hauv paus rau lubricants nyob rau hauv lub tsheb thiab aerospace industries.Nws qhov thermally ruaj khov tso cai rau kev ua siab ntev rau kev siv cua sov siab nrog txo kev sib txhuam thiab hnav thaum ua kom ntseeg tau thiab ua haujlwm.
Lwm thaj chaw uas sebacic acid pom nws siv yog nyob rau hauv kev tsim cov nplaum thiab cov tshuaj tshwj xeeb.Nws yog feem ntau siv rau hauv cov nplaum vim nws cov dej ntub dej zoo thiab nkag mus rau hauv cov khoom.Sebacic acid yog siv los tsim cov nplaum ua haujlwm siab vim nws tuaj yeem txhim kho cov khoom nplaum ntawm cov nplaum.
Sebacic acid kuj tseem siv los ua cov tshuaj tiv thaiv corrosion hauv kev kho dej thiab roj ntau lawm.Nws qhov ua tau zoo ntawm kev tiv thaiv xeb thiab oxidation ua rau nws zoo tagnrho rau cov kav dej thiab lwm yam khoom siv rau kev thauj mus los thiab ua cov roj thiab cov nkev.
Vim nws cov dawb patchy crystal cim, sebacic acid tuaj yeem txheeb xyuas tau yooj yim los ntawm lwm cov tshuaj.Qhov no ua rau nws muaj txiaj ntsig zoo rau kev lag luam kws tshuaj raws li ib qho khoom siv ntxiv.Nws tuaj yeem siv los ua ib qho diluent, binder thiab lubricant hauv kev tsim ntau hom tshuaj xws li ntsiav tshuaj, tshuaj ntsiav, thiab tshuaj suppositories.
Nyob rau hauv xaus, sebacic acid lub versatility thiab ntau yam ntawm daim ntawv thov ua rau nws ib tug heev txaus nyiam cov khoom siv nyob rau hauv ntau industries los ntawm automotive thiab aerospace mus rau kws tshuaj thiab tshuaj.Nws ruaj khov nyob rau hauv cov xwm txheej hnyav ua rau nws tseem ceeb hauv ntau qhov kev lag luam xws li yas, roj, roj, thiab kev kho dej, thaum nws lub peev xwm los txhim kho cov kev ua tau zoo ntawm cov polymers qhia nws cov nqi.Zuag qhia tag nrho, sebacic acid yog lub tsev thaiv tseem ceeb rau ntau yam khoom uas tau dhau los ua qhov tseem ceeb rau lub neej niaj hnub.
