Chiyambi cha malonda ndi zinthu zake

Sera ya parafini, yomwe imadziwikanso kuti sera ya kristalo, ndi mtundu wa sungunuka mu mafuta, carbon disulfide, xylene, ether, benzene, chloroform, carbon tetrachloride, naphtha ndi zosungunulira zina zomwe si za polar, sizisungunuka m'madzi ndi methanol ndi zosungunulira zina za polar.

gwiritsani ntchito

Parafini yosaphikidwa imagwiritsidwa ntchito kwambiri popanga machesi, fiberboard ndi canvas chifukwa cha mafuta ambiri. Pambuyo powonjezera POLYOLEFIN WOWONJEZERA KU PARAFFIN, kutentha kwake kumawonjezeka, kumamatira kwake ndi kusinthasintha kwake kumawonjezeka, ndipo imagwiritsidwa ntchito kwambiri popanga mapepala okulunga osalowa chinyezi komanso osalowa madzi, makatoni, nsalu zina ndi makandulo pamwamba.
Pepala loviikidwa mu sera ya parafini lingakonzedwe bwino pogwiritsa ntchito mapepala osiyanasiyana a sera osalowa madzi, lingagwiritsidwe ntchito muzakudya, mankhwala ndi ma phukusi ena, dzimbiri lachitsulo ndi makampani osindikizira; Parafini ikawonjezedwa ku ulusi wa thonje, imapangitsa nsalu kukhala yofewa, yosalala komanso yotanuka. Parafini ingapangidwenso kukhala sopo, emulsifier, dispersant, plasticizer, mafuta, ndi zina zotero.
Parafini woyengedwa bwino ndi parafini woyengedwa bwino amagwiritsidwa ntchito kwambiri, makamaka ngati zigawo ndi zinthu zopakira chakudya, mankhwala akumwa ndi zinthu zina (monga pepala la sera, makrayoni, makandulo ndi pepala la kaboni), ngati zinthu zophikira zophikira, zosungira zipatso [3], zotetezera zigawo zamagetsi, komanso zowongolera kukalamba ndi kusinthasintha kwa rabara [4]. Ingagwiritsidwenso ntchito popangira okosijeni kuti ipange ma acid opangidwa ndi mafuta.
Monga mtundu wa zinthu zosungiramo mphamvu yotenthetsera yobisika, parafini ili ndi ubwino wa kutentha kwakukulu kobisika kwa kusintha kwa gawo, kusintha pang'ono kwa voliyumu panthawi yosintha gawo lolimba ndi madzi, kukhazikika bwino kwa kutentha, kusazizira bwino, mtengo wotsika ndi zina zotero. Kuphatikiza apo, chitukuko cha ukadaulo wa ndege, ndege, ma microelectronics ndi ma optoelectronics nthawi zambiri chimafuna kuti kutentha kwakukulu komwe kumapangidwa panthawi yogwira ntchito kwa zida zamagetsi amphamvu kungathe kusungunuka kokha m'dera lochepa lotayira kutentha komanso nthawi yochepa kwambiri, pomwe zinthu zosinthira gawo lotsika zimatha kufika msanga pamalo osungunuka poyerekeza ndi zinthu zosinthira gawo lotsika, ndikugwiritsa ntchito mokwanira kutentha kobisika kuti zikwaniritse kuwongolera kutentha. Nthawi yochepa yoyankha kutentha ya parafini yagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga ndege, ndege, ma microelectronics ndi machitidwe ena apamwamba komanso kusunga mphamvu m'nyumba.

GB 2760-96 imalola kugwiritsa ntchito shuga wa chingamu, malire ake ndi 50.0g/kg. Yachilendo imagwiritsidwanso ntchito popanga mapepala omata a mpunga, mlingo wake ndi 6g/kg. Kuphatikiza apo, imagwiritsidwanso ntchito kwambiri popanga zinthu zosungiramo chakudya, monga chosanyowa, choletsa kuuma komanso chosagwiritsa ntchito mafuta. Ndi yoyenera kutafuna chingamu, mafuta agolide a bubblegum ndi mankhwala ndi zinthu zina komanso chonyamulira kutentha, kupukuta, kukanikiza mapiritsi, kupukuta ndi sera ina yokhudzana mwachindunji ndi chakudya ndi mankhwala (yopangidwa kuchokera ku zigawo za mafuta kapena mafuta a shale pogwiritsa ntchito kukanikiza kozizira ndi njira zina).

phukusi ndi mayendedwe

B. Chogulitsachi chingagwiritsidwe ntchito,,25KG，200KG,1000KGBAERRLS。
C. Sungani yotsekedwa m'nyumba pamalo ozizira, ouma komanso opumira mpweya. Zidebe ziyenera kutsekedwa bwino mukatha kugwiritsa ntchito nthawi iliyonse musanagwiritse ntchito.
D. Chogulitsachi chiyenera kutsekedwa bwino panthawi yonyamula kuti chisasakanikirane ndi chinyezi, alkali ndi asidi wamphamvu, mvula ndi zinyalala zina.
