Ukusebenza kwezinto ezibonakalayo

Ukumelana nokugqwala, ukufakelwa kukagesi (ikakhulukazi ukufakelwa kwemvamisa ephezulu) kuhle kakhulu, kungafakwa i-chlorine, kushintshwe imisebe, kuqiniswe ifayibha yengilazi etholakalayo. I-polyethylene ephansi inezinga lokuncibilika eliphezulu, ukuqina, ubulukhuni namandla, ukumuncwa kwamanzi okuphansi, izakhiwo zikagesi ezinhle kanye nokumelana nemisebe; i-polyethylene ephansi inokuguquguquka okuhle, ukunwebeka, amandla omthelela kanye nokuvuleka; i-polyethylene enesisindo sama-molecule ephezulu kakhulu inamandla omthelela aphezulu, ukumelana nokukhathala kanye nokumelana nokuguguleka.

I-polyethylene enengcindezi ephansi ifaneleka ekwenzeni izingxenye ezingamelani nokugqwala kanye nezingxenye zokuvikela; i-polyethylene enengcindezi ephezulu ifaneleka ekwenzeni amafilimu, njll.; i-UHMWPE ifaneleka ekwenzeni izingxenye ezimunca ukushaqeka, ezingagugi kanye nezidlulisela ugesi.

Ukusebenza kokubumba

1. Izinto ze-crystalline, ukumuncwa okuncane komswakama, akudingeki ukuthi zome ngokuphelele, zigeleza kahle kakhulu, zigeleza kahle uma zicindezelwa. Umjovo wokucindezela okuphezulu ufanelekile ekubumbeni, izinga lokushisa elifanayo lezinto, isivinini sokugcwalisa okusheshayo kanye nokubamba ingcindezi eyanele. Akufanele ukusebenzisa i-gate eqondile ukuvimbela ukugoba okungalingani kanye nokwanda kwengcindezi yangaphakathi. Naka ukukhetha indawo yesango ukuvimbela ukugoba nokuguquka.

2. Ububanzi bokuncipha kanye nenani lokuncipha likhulu, indlela eqondile isobala, kulula ukuyiguqula futhi ishintshe umbala. Ijubane lokupholisa kufanele libe lincane, futhi isikhunta kufanele sibe nezimbobo ezibandayo kanye nesistimu yokupholisa.

3. Isikhathi sokushisa akufanele sibe side kakhulu, ngaphandle kwalokho kuzobola futhi kushise.

4. Uma izingxenye zepulasitiki ezithambile zinemifantu eseceleni engajulile, isikhunta singasuswa ngenkani.

5. Ukuqhekeka kokuncibilika kungenzeka futhi akufanele kuthintane nezinyibilikisi eziphilayo ukuvimbela ukuqhekeka.

Ukusebenza kwezinto ezibonakalayo

Ukufakwa kogesi (ikakhulukazi ukufakwa kogesi okuvamise kakhulu) kuhle kakhulu, akunambala futhi kuyabonakala, izinga lokudlulisa ukukhanya lilandela ingilazi yemvelo, umbala, ukumelana namanzi, ukuzinza kwamakhemikhali kuhle. Amandla ajwayelekile, kodwa ayaphuka, kulula ukukhiqiza ukucindezeleka, ayaphuka kalula, awamelani ne-benzene, uphethiloli nezinye izinyibilikisi eziphilayo.

Ifaneleka ukwenza izingxenye zokuvikela nokubonisa izinto, izingxenye zokuhlobisa kanye nezingxenye zezinsimbi zamakhemikhali kanye nezinsimbi zokukhanya.

Ukwakha ukusebenza

1, izinto ezingasebenzi kahle, ukumuncwa komswakama okuncane, akudingeki ukuthi zome ngokuphelele, akulula ukubola, kodwa i-coefficient yokwanda kokushisa inkulu, kulula ukukhiqiza ukucindezeleka kwangaphakathi. Ukugeleza okuhle, kuyatholakala ukuze kufakwe isikulufa noma umshini wokujova we-plunger.

2. Izinga lokushisa eliphezulu lezinto ezibonakalayo, izinga lokushisa eliphezulu lesikhunta kanye nengcindezi ephansi yomjovo kuyafaneleka. Ukwandisa isikhathi somjovo kuyazuzisa ukunciphisa ukucindezeleka kwangaphakathi nokuvimbela ukushwabana nokuguquka.

3, itholakala ngezindlela ezahlukene zokuxhumanisa isango, isango kanye ne-plastic arc, ukuze kugwenywe umonakalo ezingxenyeni zepulasitiki lapho uya esangweni. Umthamo wokususa udoti mkhulu, ukuphuma kwawo kuyafana, ubukhulu bodonga lwengxenye yepulasitiki buyafana, kungcono ukungabi nama-insert, uma kukhona ama-insert, kufanele ashiswe.
