Izinto zokuvala for njengogwali ezenziwe polyethylene amagwebu: ubungakanani, iimpawu, iifoto

Xa ngokubekwa nokusebenza imibhobho naluphi na uhlobo kwakulindeleke oya kwenza eminye imithetho, kungenjalo usenokudibana zonke iintlobo iingxaki.

nemfuneko yokusebenzisa

Umjelo kunye namanzi nemibhobho, apho ibekwe ngaphandle okanye ngaphakathi amagumbi okulala, kungaba iqhwa. Ngokumalunga inkqubo ubushushu, kufuneka ufudumele, kwakunye nokugcina iqondo lobushushu ethile njengesipholisi. Ukukhuselwa kwezi meko zichazwe kusetyenziswa Izifudumezi ngenxa njengogwali ezenziwe polyethylene amagwebu.

Iimpawu eziphambili

Le nkcazelo ekhankanywe ngasentla na isakhiwo elikhethekileyo iqulathe iiseli ezincinane etywiniweyo, ingxinano wayo ilingane inani kuluhlu ukusuka ngeekhilogram-25 ukuya kuma-40 nge-cubic meter. Polyethylene uye luthambe obalaseleyo naxa baboniswa kumaqondo obushushu asezantsi, kunye neempawu zayo musa ukutshintsha uhla phakathi -60 kunye +90 degrees. Oku kubonisa ukuba ubushushu ngenxa njengogwali ezenziwe polyethylene amagwebu ingafakwa naphantsi kwazo naziphi na iimeko zemozulu. polyethylene Foamed Ukwambathisa lomlingani phezulu ngokwaneleyo, ekubeni conductivity thermal iphantsi uyohluka 0,038 ukuya 0,039. umphunga wamanzi permeability ngu 0.001, nto leyo evumela izinto ukubonisa umgangatho yenkcaso engumphunga epheleleyo. Ngayo ixhomekeke imithwalo ezahlukeneyo, yaye eyona inkulu ke kuzo oyintsobi yalowo 0.3 MPA. Zokuvala ukuba imibhobho yamanzi of polyethylene amagwebu abe ukufakwa isandi apho decibels-16, ngoko ke zokufunda entle kakhulu afunxa izandi intlokoma ezinokuthi zivele ngexesha ukusetyenziswa kweenkqubo ezisendleleni. Kufuneka kuqatshelwe kwaye hydrophobicity ubungangamsha ke xa udibana ngqo ulwelo uyakwazi wendele ngomhla wokugqibela-1% of ngumthamo opheleleyo. Izinga eliphezulu ukufakwa kwamanzi 3.5%. Kungenxa yoko le nto nesimbo akuthethi imfuno yomsebenzi ngamanzi, ekubeni umphezulu akayi kwenza condensate. Kobushushu for njengogwali ezenziwe polyethylene amagwebu entle kakhulu ukumelana nempembelelo kwezinto iikhemikhali ebonakalayo uhlobo ipetroli, i-oyile, i-asidi kwaye alkalis.

iimpawu ezongezelelweyo

ukwambathisa echazwe yenziwa ngokuhambelana GOST 30244-94. polyethylene Foamed kungenziwa zihlelwe izinto njengokuba abangaxhalabisiyo izinto ezinokutsha, ubushushu ucinezelo kulo sesichengeni ngqo nedangatye degrees 306. Kuba self-ngokwayo yi 416 degrees kwanele. Noko ke, loo nto ithathwa iadvanteji olongezelelweyo ukuba kuncinci ukwambathisa awunatyhefu kwanaxa ukutsha, kule nkqubo, oko ayikhuphi umphunga yingozi emzimbeni womntu.

iimpawu ezintle

Ukuba unomdla ubushushu ukuba imibhobho ezenziwe polyethylene amagwebu, kufuneka ucinge zonke izinto zawo. Lidla zokufunda kuthelekiswa ezinepolisterini isiponji lyu amagwebu, ngoko ungahlula eziluncedo ezininzi, phakathi kwabo - conductivity kancinane thermal, apho kunokwenzeka ukubonelela itywina olusebenzayo ene esinobukhulu encinane. Kufuneka kuqatshelwe, kunye nomgangatho efana uqine kakhulu, kwakunye nekhono elihle ukubuyisela ifomu wokuqala emva deformation. Ngomhla amagwebu enokuchaphazela isamente, gypsum, ikalika eziphathekayo, ngaphandle kwefuthe iimpawu qualitative. Ngenxa yokuba imbawula edizwe akuyongozi kwaphela, hayi kuphela abantu, kodwa singakushiyi ngasemva okusingqongileyo, uvunyelwe ukusebenzisa kolu shishino, ekhaya, ezibhedlele kwakunye nakumaziko yokudla. Polyethylene na iimpawu hydrophobicity ukuba kukwadala iimeko ezenza umntu achame kukuvela ngumngundo nangesihumba. Kufuneka kuqatshelwe, nokuchulumacha yofakelo, t. To. Products ezenziwe ngohlobo ngemibhobho ezibuhlazarha enokusetyenziswa ixesha elifutshane ukuze ukufudumeza umbhobho, esebenzisa izixhobo ezongezelelweyo kunye nezixhobo ukulungiselela le njongo. iindleko eziphathekayo ngokuphindwe-2 ngaphantsi xa kuthelekiswa ne izisombululo ezifanayo, nto leyo esisizathu sokuba olu hlobo yokugquma esetyenziswa yi abathengi ngakumbi.

Ezinye iimpawu ezimbi

ukwambathisa emhlabeni ukuze njengogwali ezenziwe polyethylene amagwebu, iimpawu ezo thaca kweli nqaku, inazo neengxaki, phakathi kwabo, njengoko kuchaziwe apha ngasentla, ukukwazi ukugcina ukutsha kunye LINGATSHA xa exposure ilangatye. Ngenxa yesi sizathu, izinto akakwazi ukusebenzisa izibonelelo ekufuneka ukuhlangabezana neemfuneko zokhuseleko umlilo omkhulu. Phakathi kwezinye izinto, alephuze amagwebu ehlala phantsi kwempembelelo kwelanga ngqo. Oku kubonisa imfuno ukugcina nokugcina umbhobho ubushushu kwezo ndawo apho ngaphandle kokungena eyingozi. Ukusombulula le ngxaki, kukho izinto lukhethiwe esingaba ngaphaya film. Iziphene lula ingahlawulwa iingenelo ikhankanywe apha ngentla.

Imilinganiselo kunye nezinye iimpawu ezithile

Ukuba ukhetha ukusebenzisa ubushushu ukuba imibhobho ezenziwe polyethylene amagwebu, ubukhulu apho ziyahluka ukusuka-6 ukuya 160 mm, kuyimfuneko ukwazi zonke iintlobo ngobubanzi balo. Ngenxa yoko, Ebubanzini bodonga inokuba kulingana inani kuluhlu emithandathu ukuya kumashumi amathathu anesibini iimilimitha. Imarike unako ukufumana yokugquma kumbhobho, apho babonelelwa inwebu okhethekileyo, ukuba ukutyabeka esinombala polymeric. It likhusela ngokuchaseneyo elangeni, nto leyo evumela ukusetyenziswa kwezi mveliso, nokuba kwiindawo bajikelezwe ukuba kweultraviolet ukukhanya. Phakathi kwezinye izinto, ezisongwayo ukuba imibhobho ezenziwe polyethylene amagwebu, apho imifanekiso lucaciswa kule nqaku inokuba sheet okanye umqulu. Ngamaxesha yezandla okanye yokugquma intw oyiphanzise ngcina.

Ubume yeqokobhe

ifomu Kufuneka ukuhlangabezana neemfuno ezithile ezikuvumela ukuba ukulujikeleza umgangatho kunye izikhewu engephi. Le nkcazelo kufuneka gqitha, yaye le fom kufuneka enobubanzi ethile. Kuphela ngale ndlela kuya kuba nako ukunika umlinganiselo elibalulekileyo usambathisa. Ukuqinisekisa ukufakwa lula ecaleni ityhubhu, njengoko umthetho, ukuba liqatywe zeteknoloji, nto leyo evumela ukwenza umsebenzi wofakelo kweli xesha lifutshane kangangoko kunye neenkqubo esele ifakiwe.

Iimpawu yokumiswa

Ukuba ugqiba ukuyisebenzisa ngenxa yokugquma, ezisongwayo ukuba imibhobho ezenziwe polyethylene amagwebu, ubukhulu kuyimfuneko ukukhetha kakhulu ogqibeleleyo. Emva koko, kubalulekile ukulandela ufakelo zobugcisa usambathisa. Ngemibhobho belungiselelwe nkqubo, kwaye umphezulu kwabo icocwe ukusuka ukungcola nothuli. Polyethylene ubekwa phezu uhlobo lelonani ukuba ukuhlanganiswa kunye neengxaki ezithile. Oku kunokwenziwa kumbhobho kodwa ifakiwe, i ezisongwayo abayi yonakele ngemela.
