Okwangoku, isetyenziswa rhoqoIzixhobo zokufakwaIintambo ze-DC yi-polythylene. Nangona kunjalo, abaphandi baqhubeka nokufuna izixhobo zokufakwa ezinokubakho, ezinjenge-polypropylene (PP). Nangona kunjalo, usebenzisa i-PP njengemiba yokuthambisa intambo kuzisa iingxaki ezininzi.
1. Iipropathi zoomatshini
Ukufezekisa iimfuno ezisisiseko zothutho, ufakelo, kunye nokusebenza kweentambo zeDC, izixhobo zokufakelwa kufuneka zibe namandla athile okungoomatshini, kubandakanya bhetyebhetye kakuhle, kunye nokunganyangekala kobushushu obuphantsi, kunye nokunganyangeki kweqondo lobushushu eliphantsi, kunye nokunganyangeki kweqondo lobushushu eliphantsi. Nangona kunjalo, i-PP, njenge-crystalline ye-crystalline, ibonise i-gigidity ngaphakathi kwendawo yalo yobushushu esebenzayo. Ukongeza, ibonisa ubuchule bokukrazula kunye nokuzibandakanya ekuqhekezeni kwiindawo zobushushu eziphantsi, ukusilela ukufezekisa le meko. Ke ngoko, uphando kufuneka lugxile ekuchitheni nasekuguquleni i-PP ukulungisa le micimbi.
2. Ukunganyangeki
Ngexesha lokusetyenziswa kwexesha elide, i-DC ye-DC ye-DC ngokuthe ngcembe iminyaka ngenxa yefuthe elidityanisiweyo lobungakanani bendawo ephezulu yombane kunye nebhayisikile ye-thermal. Olu gadalala lukhokelela ekunciphiseni kwepropathi kunye ne-inshonter, kunye nokwehla kwamandla aqhekekileyo, ekugqibeleni kuchaphazela ukuthembeka kunye nenkonzo yenkonzo yentambo. Ukwaluphala kwentambo kubandakanya oomatshini, oombane, i-thermal, kunye neekhemikhali, ukugugaka kombane kunye ne-thermal yeyona ndlela. Nangona ukongeza i-antioxidants kunokuphucula ukuxhathisa i-PP kwi-thermal ye-thermal gaidage ukuya kuthi ga kwinqanaba elithile, ukulunga phakathi kwe-antioxididants kunye ne-PP, imfuduko, kunye neezongezo zichaphazela intsebenzo ye-PP. Ke ngoko, sixhomekeke kuphela kwi-Antisoxidants ukuphucula ukunganyangeki kwe-PP akunakuhlangabezana neemfuno zobomi kunye nokuthengisa ukuthengiswana kwe-DC I-DC, kunyanzelisa uphando olongezelelekileyo kwi-PP.
I-3. Umsebenzi wokufakelwa
Intlawulo yendawo, njengenye yezinto ezithambekele kumgangatho kunye nobomi beI-voltage ephezulu ye-DC, ichaphazela kakhulu ukuhanjiswa kwendawo yombane yendawo, amandla ediliya, kunye nokufakelwa kwempahla. Izixhobo zokufaka i-insumpas ze-DC kufuneka zicinezele ukuqokelelwa kweSithuba, ukunciphisa inaliti yokuthintela indawo yombane, kwaye kuthintele isizukulwana sombane ukuthintela i-inshonsions kunye ne-cable yase-Insepan.
Xa i-DC I-DC ihleli kwintsimi yombane engasenzi ixesha elide, ii-elektroni, i-ion, kunye nokungcola okuveliswayo kwimibandela yokufakwa kwe-electroni kuya kuba ziindleko zendawo. Ezi ntlawulo zifuduka ngokukhawuleza kwaye ziqokelele kwiipakethi ezihlawulwayo, ezaziwa ngokuba nokuqokelelwa kwentlawulo yendawo. Ke ngoko, xa usebenzisa i-PP kwi-DC I-DC, uhlengahlengiso luyimfuneko ukucinezela ukuvelisa kunye nokuqokelelwa.
4. Ukuqhubela phambili kwenkunkuma
Ngenxa yokuqhutywa kwe-shirmal engalunganga, ubushushu obuveliswe ngexesha lokusebenza kwe-DC ye-DC ayinakukwazi ukudambisa ngokukhawuleza, kukhokelela kumacala onobushushu phakathi kwentsimi ye-inshurensi, ukudala intsimi yobushushu obungalinganiyo. Ukuqhutywa kombane kwezixhobo ze-polymer kunyuka ngamaqondo obushushu anyukayo. Ke ngoko, icala langaphandle lomthengisi lokufakelwa ngempumelelo esezantsi libathanga ukuthengisa ukuqokelela, okukhokelela ekunciphiseni ubukhulu becala. Ngaphezulu, amaqondo obushushu abangela inaliti kunye nokufuduka kwenani elikhulu leendleko zendawo, zigqwetha ngakumbi intsimi yombane. Iqondo elikhulu iqondo lobushushu, indawo yokuhlawula isithuba senzeka, yandisa ukugqobhoza kwendawo yombane. Njengoko bekuchaziwe ngaphambili, ubushushu obuphezulu, ukuqokelelwa kwesithuba, kunye nokugqobhoza kwendawo yombane kuchaphazela ukusebenza kwesiqhelo kunye nobomi benkonzo be-DC ye-DC. Yiyo loo nto ukuphuculwa kokuphunyezwa kwe-PP ye-PP kubalulekile ukuqinisekisa ukusebenza ngokukhuselekileyo kunye nenkonzo yexesha elide yobomi be-DC.
