Okwangoku, uninzi lwabavelisi bokusetyenzwa komngundo benaliti basebenzisa ngokusisisekoinaliti ye-bakeliteoomatshini bokubumba kunyeinaliti yeplastikioomatshini bokubumba.Kukho iiyantlukwano ezahlukeneyo phakathi koomatshini bokubumba be-bakelite be-bakelite kunye noomatshini bokubumba inaliti yeplastiki.I-Bakelite yi-PF (phenolic resin).I-Bakelite luhlobo lweplastiki yemveliso yokuqala, eyathi yaqonda imveliso yoshishino e-United States ngo-1910. Makhe sibone ukuba yintoni umahluko?
Iimathiriyeli ekrwada yokuvelisa i-bakelite ikakhulu ziiphenols kunye ne-aldehydes, kwaye i-phenol kunye ne-formaldehyde zisetyenziswa ngokuqhelekileyo.Zifunyenwe nge-polycondensation phantsi kwe-catalysis ye-asidi, i-alkali kunye nezinye ii-catalysts.Imveliso yezoshishino ikakhulu ibandakanya inkqubo eyomileyo kunye nenkqubo emanzi.
I-Phenol kunye ne-aldehyde inokuvelisa iintlobo ezimbini ze-PF phantsi kwesenzo se-catalysts ezahlukeneyo: enye i-thermoplastic PF kwaye enye i-thermosetting PF.Eyangaphambili inokunyangwa ibe kulwakhiwo lomzimba kuphela ngokongeza iarhente yokunyanga kunye nokufudumeza, ngelixa umva unokuba sisakhiwo somzimba nje ukufudumeza ngaphandle kwearhente yokunyanga.
Nokuba i-pf ye-thermoplastic okanye i-PF ye-thermosetting, kuphela inethiwekhi yotshintshiselwano eyenziwe ngokuphilisa ingasetyenziswa.Inkqubo yokunyanga kukuqhubela phambili kwempendulo ye-polycondensation eninzi kunye nokwakhiwa kwemveliso yokugqibela.Le nkqubo ihluke ekunyibilikeni kunye nokunyangwa kwe-thermoplastic jikelele.Ayinakuguqulwa, kuquka zombini iinkqubo zomzimba kunye neekhemikhali.
I-PF inokubunjwa ngendlela efana ne-thermoplastic.I-Pf esetyenziselwa ukubumba inaliti ifuna ubumanzi obulungileyo, ukubumba phantsi koxinzelelo lwenaliti ephantsi, ukuqina okuphezulu kwe-thermal kunye nesantya esikhawulezayo sokuqina, iglosi elungileyo kumphezulu wamalungu eplastiki, ukudilizwa ngokulula kwaye akukho ngcoliseko kubumba.Nangona kunjalo, ukubumba inaliti nako kuneentsilelo zako.Ngokomzekelo, ukunyibilika kukhawulelwe luhlobo lokuzalisa, alufanelekanga ukubumba iindawo zeplastiki kunye nokufakwa okungaphezulu, kunye nenani elikhulu lamasango kunye nemijelo yokuhamba emva kokunyanga ayikwazi ukuphinda isetyenziswe kwaye ingalahlwa kuphela.
Ngamafutshane, i-PF ye-thermoplastic inokuveliswa ngumatshini wokubumba oqhelekileyo, kodwa iimeko zenkqubo kufuneka zilawulwe ngokungqongqo.I-Thermosetting pf kufuneka iveliswe ngumatshini wokubumba okhethekileyo we-PF (umgqomo kunye nesikrufu zahlukile kumatshini wokubumba wenaliti eqhelekileyo), kwaye umngundo kufuneka usebenzise isakhiwo soyilo esikhethekileyo!
ISino Vision Vehicle & Service Co., Limited, ibekwe kwidolophu yaseHuangyan, eTaizhou, igxile ekusetyenzweni kwesitofu sokubumba okufana ne-bakelite, ukubumba inaliti ye-BMC kunye nokubunjwa kwenaliti yeplastiki echanekileyo.Iimveliso zokubumba ze-Bakelite kunye ne-BMC zisetyenziswa ngokubanzi kuzo zonke iintlobo ze-kitchenware, i-electromechanical kunye ne-appliance appliance yasekhaya.Inkampani inobunjineli obuqinileyo kunye neqela lobugcisa, elizinikele ekudaleni iimveliso ezinomgangatho ophezulu kunye nexabiso elihle kubathengi, elinokuthi lihlangabezane neemfuno ezahlukeneyo zokulungisa abathengi.
