Isinqandi ebomvu kunye nezinye izimvo zakhe

Isinqandi yi ulwelo ogama lobushushu asezantsi kakhulu lobushushu crystallization ukuba amanzi qhwa. Ukusebenzisa le ulwelo inceda ukuthintela umonakalo iindlela ezinokwenzeka xa H2O crystallization. Isinqandi (ebomvu, omthubi, oluhlaza, njl) ibandakanya amanzi kunye a utywala polyhydric. Ukongeza, i-njengesipholisi ongezwe ongeziweyo ezahlukeneyo, umhlwa amacandelo exhathisayo ngokunjalo. Ezi zihlanganisi ezongezelelweyo igalelo iinkcukacha ukukhuselwa. Njengenxalenye kulwelo ikwaqulathe idayi, leyo ubanike umbala othile. Ngokutsho izimvo leengcali, umbala engamanzi alunasiphumo kwi yokusebenza yayo. Ngokuhambelana kunye umda, zinendlela (ebomvu kunye nezinye iintlobo zalo) ukuze kubandakanye ethylene ethers okanye propylene ethers.

Le yokugqibela yi ulwelo ezingenambala viscous ezinamafutha. Kuye ivumba kuphawu ityhafile. Ethylene ethers i netyhefu kakhulu, ngoko ke lumka xa ulibamba kubo. Pure ethers ethylene emkhenkceni Degrees ezilishumi. ukwandiswa kwendawo yokuhlala yayo degrees 197. Kufuneka ke ukuba ethers ethylene kwi isicombululo kanzulu zolwelo ngumkhenkce kwiqondo eliphantsi (xa kusetyenziswa iinxalenye ezimbini ethylene ethers enye yamanzi inxenye). Ukupheka indawo isinqandi ngokomlinganiselo imalunga elikhulu elinamanci mabini degrees, kwaye ubuncinane qhwa kwayo abe degrees asixhenxe ngasezantsi zero. Njengomgaqo, zinendlela (ebomvu, otyheli, njl) iqulathe kumafa yayo malunga 50-60% ethylene ethers. Kulo mzekelo, ke ilingana ubushushu neGauteng ubuncinane degrees amathathu ngaphantsi zero.

Ekwenziweni emelana ngayo kwakhona ngokufuthi zisetyenziswa propylene ethers. Le nto okusingqongileyo. Kulo mzekelo, intsebenzo phantse ezimeleyo wenqwelwana. Noko ke, propylene ethers indlela ekhuselekileyo kwaye ayinabungozi.

Igama elithi "anti-ngumkhenkce" linokuguqulelwa ngokuthi "anti-iqabaka" okanye "ice-free". Eli gama lisetyenziswa ukubhekisela zonke brand of coolants.

Isinqandi okanye isinqandi - kokona kulungileyo?

Kufuneka kuqatshelwe ekuqaleni le ngcamango lokuqala lisetyenziswa ukubhekisela ziincindi imveliso yasekhaya. Igama elithi "zinendlela" iqulethe igama khadi, apho kuyo kwathiwa yenzelwe (Organic Udibaniso Technologies Division (CBT)). Imisa "ol" libhekisela izinto kwalo utywala. Isinqandi ibhekisa coolants yemveli kuzisebenzisa ngakumbi nangakumbi ngamaxesha.

Njengoko sele sibonile, iimpawu yokusebenza izinto asixhomekeki nokuba lo isinqandi - ebomvu, bhlowu, mthubi, okanye ngaphezulu nawuphi na umbala. Ekuqaleni, bonke ulwelo zenziwa umbala ofanayo. Isinqandi idayi ingeza "ubuntu." Ezithile Kukholelwa ukuba ukuba indlela elisetyenziswa ngayo ulwelo umbala ofanayo omnye komnye. Kufuneka kuqatshelwe ukuba ezilahlekisayo ezininzi. Nokupakishwa of nokubanda umenzi usoloko unika imiyalelo ukuya izakhono ukuxubana yohlobo yayo nabanye.

Ngelo lixa umgangatho ethile karhulumente iye yenziwa ukwenzela kwiincindi zasekhaya. Nakuba kunjalo, kufuneka kuqatshelwe ukuba ekulandeleni olungagungqiyo GOST akusosiqinisekiso iimpawu zazo kwizinga eliphezulu. Umzekelo, zinendlela imveliso Russian azisoloko isicelo amacebo mihla le injini. Kulo mzekelo, yaseYurophu anti-ngumkhenkce ayikho efanelekileyo ngomgangatho Russian, bonisa intsebenzo ekumgangatho ophezulu.
