Chiyambi cha malonda ndi mawonekedwe ake

Sera ya parafini, yomwe imatchedwanso crystal sera, ndi mtundu wa sungunuka mu mafuta, carbon disulfide, xylene, ether, benzene, chloroform, carbon tetrachloride, naphtha ndi zosungunulira zina zopanda polar, zosasungunuka m'madzi ndi methanol ndi zosungunulira zina za polar.

ntchito

Paraffin waiwisi amagwiritsidwa ntchito makamaka popanga machesi, fiberboard ndi canvas chifukwa chokhala ndi mafuta ambiri.Mukawonjezera POLYOLEFIN ADDITIVE KU PARAFFIN, malo ake osungunuka amawonjezeka, kumamatira kwake ndi kusinthasintha kwake kumawonjezeka, ndipo amagwiritsidwa ntchito kwambiri popanga mapepala okulunga otetezedwa ndi chinyezi komanso madzi, makatoni, zokutira pamwamba pa nsalu ndi makandulo.
Mapepala omizidwa mu sera ya parafini akhoza kukonzedwa ndi ntchito yabwino yopanda madzi ya pepala la sera zosiyanasiyana, angagwiritsidwe ntchito mu chakudya, mankhwala ndi ma CD ena, dzimbiri lachitsulo ndi makampani osindikizira;Parafini ikawonjezeredwa ku thonje, nsaluyo imatha kupangitsa nsalu kukhala yofewa, yosalala komanso yotanuka.Parafini imathanso kupangidwa kuti ikhale yotsukira, emulsifier, dispersant, plasticizer, mafuta, etc.
Parafini woyengedwa bwino kwambiri ndi parafini woyengedwa bwino kwambiri amagwiritsidwa ntchito kwambiri, makamaka ngati zigawo ndi zida zoyikamo chakudya, mankhwala amkamwa ndi zinthu zina (monga pepala la sera, makrayoni, makandulo ndi pepala la kaboni), ngati zida zopangira zophika, zosungira zipatso. [3], pakutchinjiriza kwa zida zamagetsi, komanso kukonza zoletsa kukalamba komanso kusinthasintha kwa mphira [4].Itha kugwiritsidwanso ntchito ngati okosijeni kuti apange mafuta acids opangira.
Monga mtundu wa zinthu zobisika kutentha mphamvu yosungirako, parafini ali ndi ubwino waukulu zobisika kutentha kwa gawo kusintha, pang'ono voliyumu kusintha pa olimba-zamadzimadzi gawo kusintha, wabwino matenthedwe bata, palibe undercooling chodabwitsa, mtengo wotsika ndi zina zotero.Kuonjezera apo, chitukuko cha ndege, ndege, ma microelectronics ndi optoelectronics teknoloji nthawi zambiri amafuna kuti kutentha kwakukulu komwe kumapangidwa panthawi yogwiritsira ntchito zigawo zamphamvu kwambiri kungathe kutayika m'dera lochepa la kutentha kwapakati komanso nthawi yochepa kwambiri, pamene yotsika kwambiri. Zinthu zosinthira gawo losungunuka zimatha kufika msanga posungunuka poyerekeza ndi zida zosinthira gawo losungunuka, ndikugwiritsa ntchito mokwanira kutentha kobisika kuti mukwaniritse kutentha.Nthawi yayifupi yoyankha kutentha kwa parafini yakhala ikugwiritsidwa ntchito kwambiri m'malo osiyanasiyana monga ndege, zamlengalenga, ma microelectronics ndi machitidwe ena apamwamba kwambiri komanso kupulumutsa mphamvu zanyumba.[5]
GB 2760-96 amalola kugwiritsa ntchito chingamu shuga m'munsi wothandizira, malire ndi 50.0g/kg.Zakunja amagwiritsidwanso ntchito pomata pepala kupanga mpunga, mlingo wa 6g/kg.Kuonjezera apo, amagwiritsidwanso ntchito kwambiri pazinthu zopangira chakudya, monga chinyezi, anti-sticking ndi mafuta.Ndi oyenera chakudya kutafuna chingamu, bubblegum ndi mankhwala zabwino golide mafuta ndi zigawo zina komanso kutentha chonyamulira, demolding, piritsi kukanikiza, kupukuta ndi sera zina mwachindunji kukhudzana ndi chakudya ndi mankhwala (opangidwa kuchokera phula tizigawo ta mafuta kapena shale mafuta ndi kukanikiza ozizira ndi njira zina).

phukusi ndi transport

B. Izi angagwiritsidwe ntchito,, 25KG, 200KG, 1000KGBAERRLS.
C. Sungani chosindikizidwa mu malo ozizira, owuma ndi mpweya wokwanira m'nyumba.Zotengera ziyenera kutsekedwa mwamphamvu mukatha kugwiritsa ntchito chilichonse musanagwiritse ntchito.
D. Mankhwalawa ayenera kusindikizidwa bwino panthawi yoyendetsa kuti ateteze chinyezi, alkali wamphamvu ndi asidi, mvula ndi zonyansa zina kuti zisasakanike.
