1. Ukusekwa kwesikali sokubumba
Ukungunda komngundo kwenzeka phantse kuyo yonke i-thermoplastics ngexesha lenaliti yokubumba. Xa iimfuno zokusebenza zemveliso yokugqibela kufuneka zixutywe nezongezo ezifanelekileyo (ezinje ngesiguquli, isiciko somlilo, njl.njl.), Ezi zongezo zinokwenzeka ukuba zihlale kumphezulu womngundo ngexesha lenkqubo yokubumba, zikhokelela ekubunjweni komngundo isikali.
Kukho ezinye izizathu zokwenziwa kwesikali sokubumba, izizathu eziqhelekileyo zezi zilandelayo:
Iimveliso zokubola kwezobushushu zempahla ekrwada;
Ngexesha lenaliti yokubumba, amandla okucheba okugqithisileyo okunyibilika kokunyibilika kwabonwa;
Ukukhupha okungafanelekanga;
Isikali sokubumba esingasentla sihlala sidibanisa izinto ezahlukeneyo, kwaye kunzima kakhulu ukufumanisa ukuba yintoni ebangela isikali sokubumba kunye nendlela yokuthintela, kwaye isikali sokubumba asizukubakho kude kube ziintsuku ezimbalwa kamva.
2. Uhlobo lwesikali sokubumba
1) izongezo ezahlukeneyo ukuvelisa iintlobo ezithile isikali sokubumbela. Ukudodobalisa umlilo kuya kusabela kubushushu obuphezulu ukwenza ukubola kwaye kunokuvelisa iimveliso zesikali. Ngaphantsi kwefuthe lobushushu obugqithisileyo okanye uxinzelelo olugqithisileyo lwe-shear, iarhente yempembelelo iya kwahlulwa kwipolymer kwaye ihlale kumphezulu womngundo womngundo ukwenza isikali sokubumba.
2) Ukunyibilika kombala kwiiplastikhi zobunjineli be-thermoplastic kubushushu obuphezulu kuya kunciphisa uzinzo olushushu lwezixhobo zokubumba, okukhokelela ekwenziweni kwesikali ngokudityaniswa kweepholima eziwohlokileyo kunye neebala ezibolileyo.
3) iindawo ezishushu ikakhulu (ezinje ngomngundo cores), iimodareyitha / izinto ezizinzileyo kunye nezinye izongezo zinokubambelela kumphezulu wokubumba kwaye zibangele ukungcola. Kule meko, kufuneka kuthathwe amanyathelo okuphumeza ulawulo lobushushu olungcono okanye ukusebenzisa izinto ezizinzileyo.
Olu luhlu lulandelayo luluhlu lwezinto ezinokubangela isikali sokubumba kunye namanyathelo othintelo:
3. Izinto zokulwa zokwenziwa kwesikali ngequbuliso
Ukuba isikali sokubumbasenzeka ngesiquphe, kusenokubangelwa kukutshintsha kweemeko zokubumba okanye ukutshintsha kweebhetshi ezahlukeneyo zezinto zokubumba. Ezi ngcebiso zilandelayo ziya kunceda ukuphucula isikali sokubumba.
Okokuqala, linganisa iqondo lobushushu lokunyibilika kwaye ujonge ngokubonakalayo ukuba ngaba kukho imeko yokubola (ezinje ngamasuntswana anyukayo). Kwangelo xesha, jonga ukuba ngaba izinto zokubumba zingangcoliswa zizinto zangaphandle nokuba kusetyenziswa izinto ezifanayo zokucoca. Qwalasela imeko zeemoto sokubumba.
Kwakhona, jonga ukusebenza komatshini: sebenzisa izinto zokubumba ezinemibala (ngaphandle komnyama), emva kwemizuzu engama-20, vala umatshini wokubumba inaliti, susa umlomo kunye nesihlalo sokudibanisa, ukuba kunokwenzeka, uqhaqhe ngesikrufu, khangela ukuba zikhona amasuntswana atshisiweyo kwizinto zokwenza imveliso, thelekisa imibala yezinto ekrwada, kwaye ngokukhawuleza ufumane umthombo wesikali sokubumba.
Kwiimeko ezininzi, kuye kwafunyanwa oonobangela bokothuka kweziphene. Obu buchwephesha bulungele kakhulu oomatshini abancinci bokubumba inaliti enobubanzi obukhulu be-40mm. Ukupheliswa kwesikali sokubumba nako kunokuphucula umgangatho weemveliso. Le ndlela yokuchasana ingasentla iyasebenza nasekwenzeni inkqubo yembaleki eshushu.
Isikali zomngundo sibangela ukubonakala kweziphene kumalungu abunjiweyo enaliti, ngakumbi iindawo ezinomhlaba ongaphezulu, ezinokulungiswa ngumatshini wesanti.
4. ulondolozo lomngundo
Xa onke la manyathelo angentla engenakususa isikali sokubumbela, ulondolozo lwesikhunta kufuneka luqiniswe.
Isikali sokubumbela kumphezulu womngundo kulula ukusisusa kwinqanaba lokuqala, ngoko ke umngundo kunye nomjelo wokukhupha kufuneka ucocwe kwaye ugcinwe rhoqo (umz.emva kokuba ibhetshi nganye yemveliso yokubumba). Kunzima kakhulu kwaye kuthatha ixesha ukususa isikali sokubumba emva kokuba isikhunta senza umaleko otyebileyo ngaphandle kokugcinwa komngundo kunye nokugcinwa ixesha elide.
Ukugcinwa kwenaliti kunye nokugcinwa kwesitshizi esisetyenzisiweyo ikakhulu: iarhente yokukhupha ukungunda, i-rust inhibitor, ioyile ye-thimble, isusa ibala lokususa ibala, iarhente yokucoca ukungunda, njl.
Ukwenziwa kweekhemikhali zesikali sokubumba kuyinkimbinkimbi kakhulu, kwaye kufuneka kusetyenziswe iindlela ezintsha kwaye kuzanywe ukusisusa, njengezinyibilikisi ngokubanzi kunye nezinyibilikisi ezikhethekileyo ezahlukeneyo, ukutshiza nge-oveni, ilamunade enecaffeine, njl. umkhondo.
Ukucocwa koxinzelelo lwenaliti yenaliti yeeplastiki zobunjineli
5. Iingcebiso kuthintelo isikali sokubumba
Xa kusetyenziswa imbaleki eshushu kunye nobushushu bempahla ekrwada, ixesha lokunyibilika liza kuba lide, nto leyo eyonyusa umngcipheko wokubekwa kwesikali ngenxa yokubola kwezinto zokwenza imveliso. Ukucoca isihlunu somatshini wokubumba.
Imbaleki yesayizi enkulu kunye nesango zisetyenziselwa ukwenza izixhobo zokucheba ezibuthathaka. Inqaku lesango elininzi linokunciphisa umgama wokuhamba, isantya sejenisi esezantsi kunye nokunciphisa umngcipheko wokubumba isikali sokubumba.
Ukuphela kokufa okufanelekileyo kunokunciphisa ukubakho kwesikali sokubumba, kunye nokukhutshwa kwesikhunta esifanelekileyo kufuneka kubekwe kwinqanaba loyilo lokungunda. Olona khetho lufanelekileyo kukususa ngokuzenzekelayo inkqubo yokukhupha okanye ukususa ngokulula isikali sokubumba. Ukuphuculwa kwenkqubo yokukhupha kuhlala kukhokelela ekunciphiseni isikali sokubumba kumbumba.
Ukutyabeka okukhethekileyo okungekho ntonga phezu komphezulu wokufa kunokuthintela ukuyilwa kwesikali sokubumba. Iziphumo zokwaleka kufuneka kuvavanywe kuvavanyo.
Unyango lwe-titanium nitride kumphezulu wangaphakathi wesikhunta unokuthintela ukuyilwa kwesikali sokubumba.
