IHDPE tube: iimpawu kunye nezicelo

izincedisi zeplastiki ukuba imibhobho wabonakala kwilizwe lethu malunga phakathi 90 zenkulungwane yokugqibela, emva koko phantse nangoko indawo oothixo zentsimbi nensimbi. Oku kuyinyani ngakumbi kwemibhobho yamanzi. Kubonakala ukuba eli xesha ipipi iHDPE (iimpawu apho thina uchaze ngezantsi), wazingqina ngokwabo ukuba nkulu, kodwa abanye bethu nangoku yeplastiki kukulumka ethile. Makhe sithethe okungakumbi ngale mveliso.

Ukususela oko ezi iityhubhu zenziwa?

Ithekhnoloji ivelisa abanjalo ukuba ethylene iimolekyuli inkqubo crosslinking lwenzeka noxinzelelo-5 kg / cm ^2. Kwakheka izinto kunye ukuxinana 0,941 g / cm, ukuba ukuqina elungileyo. Ngenxa isakhiwo ngumkhenkce, oko lokukhanya ezahlukeneyo. Njengoko ethylene into siqhagamshelwe zinemoletyhule indawo kunye eyayizalwa encinane, inqaba zezinto ezithile eziziphumo liphezulu kakhulu. IHDPE linyibilike kubushushu ngeedegree-130, ukwenzela ukuba ukusetyenziswa ibhanile iimveliso kukhulula yoloyiko abanalo ukusilela ngenxa lobushushu factor akufanele yini. Ngenxa yoko, umbhobho iHDPE, iimpawu zazo kakuhle kangaka, ephelele amakhaya iinkqubo zokuzisa amanzi zabucala.

Ukongeza, ukuba enokumelana elihle asidi kunye amafutha, nto leyo eyenza imibhobho loo mgqatswa kangangoko for obandayo yesidala nje kuphela, kodwa indle. Kufuneka kuqatshelwe ukuba nayo oqhiphuke umbilini, kodwa ngokusebenzisa amanqaku aphezulu-ezinto ukuba akuyi kwenzeka phantsi kweemeko ezithile. Enyanisweni, umbhobho iHDPE, iimpawu ezo kakhulu eziphakamileyo, sifakwa kwiqondo lobushushu ukuya ku -50 degrees Celsius.

Ukongeza, iHDPE iveliswa umboniso ukupakisha, imibhobho ezisongwayo ukuba iintambo eliphezulu-ombane, iminatha ngenxa iingcingo, ifanitshala kunye nempahla ngokwawo, kunye noluhlu kakhulu zezinye izinto.

Eyona engundoqo iimpawu imveliso

Noko ke, amaqela anomdla asikho kakhulu iimpawu zobugcisa iminatha kunye izincedisi, njengokuba ngqo kwimibhobho ngokwabo. Makhe sijonge ngokweenkcukacha ezingakumbi.

Okokuqala, impilo inkonzo - ubuncinane isiqingatha senkulungwane. Bemithi 50 ngayo kwinkulungwane yokugqibela wabeka nozinzo enjalo kuyilo zabo. Njengokuba besesitshilo, ukuba ingenathamsanqa lakufumana imeko yemichiza ndlongondlongo. Ngaphezu koko, imibhobho ezenziwe polyethylene asingabo imisinga eziyabulayo, ngoxa imibhobho yesinyithi zinokutshatyalaliswa nabo kuphela namaxesha eziliqela. Nditsho iindleko ngokubekwa kwabo ngezantsi phantse umyalelo ubukhulu: ekugqibeleni, ukuba kuyimfuneko, ukumelana nalo msebenzi, nokuba ngumntu omnye. Kwaye konke oku - umbhobho iHDPE. umkhuba Technical yokusebenzisa iye yabonisa ukuba nkqu umhlwa yokuba ukuyilwa, kangangokuba imfuneko Babesinqinda nomonakalo nezixhobo ungakhohlwa ngokukhuselekileyo.

Qaphela ukuba nokuba kumaqondo obushushu asezantsi kakhulu ngumsindo, ezikhokelela komsipha iimveliso zesinyithi eqhelekileyo, polyethylene kuhlala ayiphazanyiswa ngokupheleleyo. Oku kubangelwa yinto yokuba conductivity wobushushu kwale nto iphantsi kakhulu. nto umbhobho iHDPE (iimpawu apho reviewed) ukuze kakuhle ngokulinganayo kusetyenziselwa kuphela kwimozulu epholileyo, kodwa ke oko Far North. Hi ndlela leyi, nokuba kumaqondo obushushu asezantsi kakhulu, xa amanzi nangoku engumkhenkce ngaphakathi imveliso, akukho nto yoyikekayo kuya kwenzeka: a polyethylene ukwandisa nge 5-7%, ukuze ukuba umkhenkce akayi kuba nako linyothule up.

Le propati ekwazi ukumelana elihle waterhammer, ukuze nkqu ezihlekisayo iinkonzo zoluntu akuthethi akoyikise. Ukuba into eyenzekayo, wokulungisa ayisayi kuthatha ixesha elininzi. Ukongeza, umbhobho iHDPE, iimpawu apho zivumele iwelding yayo, kunye ixesha angalahlekelwa amandla nokuba welds.
