Umaleko wokugquma umbhobhoukwabizwa ngokuba ngumaleko wokugquma wemibhobho eshushu, ebhekisa kumaleko ajikelezwe kumbhobho onokudlala indima yogcino lobushushu kunye nokugquma ubushushu.Umaleko wokugquma wemibhobho udla ngokuqulunqwa ngamaleko amathathu: umaleko wokugquma, umaleko okhuselayo, kunye nomaleko ongangeni manzi.Ukugqunyelelwa kwemibhobho yoshishino kubalulekile kwaye kunoqoqosho.Iqinisekisa ukuhanjiswa okuqhelekileyo kolwelo kunye negesi kumbhobho, inciphisa ilahleko yamandla, yandisa ubomi benkonzo yombhobho, kwaye igcina izibonelelo zoqoqosho.Ezi ziinzuzo zeukugqunywa kwemibhobho.
Kwimibhobho yerabha kunye neplastiki yokugqunywa kweplastiki, abasebenzi beNkampani yeTekmax baqala ukulinganisa imilinganiselo yemibhobho egqunyiweyo, iitanki, njl. Ukwakhiwa kwe-insulation sheet kunye nokusonga iphepha lentsimbi Kwimibhobho kunye neetanki ezifuna ukugqunywa, sebenzisa iingcingo zetsimbi ukuze uzibophe ukukhusela ulusu lwesinyithi ukuba lungawi.Iyunithi yokwakha nayo ifuna ukugubungela ngononophelo iindawo eziphakanyisiweyo njengemibhobho kunye nezixhobo zokuqinisekisa umphumo olindelekileyo we-thermal insulation.
1 I-insulation of pipelines kunye nezixhobo kufuneka zihlambuluke kwimijelo kunye nemigodi ye-tube, kwaye i-insulation ingenziwa kuphela xa kungekho monakalo ongaphezulu kwi-insulation layer kwinkqubo elandelayo.
2 Ngokuqhelekileyo, ukugquma kwemibhobho kufuneka kufaneke kuvavanyo loxinzelelo lwamanzi, kwaye i-anti-corrosion inokwakhiwa kuphela, kwaye inkqubo ayikwazi ukuguqulwa.
3 Irabha kunye nezinto zokugquma zeplastiki akufuneki zibekwe emvuleni okanye zigcinwe kwindawo ezifumileyo xa zingena kwisiza.
4 Inkunkuma eshiywe emva kokugcinwa kobushushu kufuneka icocwe liqela elinoxanduva lokwakha.
5 Kwi-thermal insulation yemibhobho eveziweyo, ukuba imisebenzi ye-civil ifafaziwe, kufuneka kubekho imilinganiselo yokuthintela ukungcoliswa kwe-thermal insulation layer.
6 Ukuba kukho iimeko ezikhethekileyo ezifuna ukususa i-insulation layer yonyango lwemibhobho okanye ezinye iintlobo zomsebenzi zonakalisa umaleko we-insulation ngexesha lokwakha, kufuneka zilungiswe ngexesha ngokweemfuno zokuqala.
Namhlanje, umhleli uya kukucacisela iindlela ezininzi zokugqunywa kwemibhobho yeshishini.
1. Ukufakwa kwe-polyurethane foam
KwiProjekthi ye-Shaanxi Pipeline Thermal Insulation Project, umbhobho ongcwatywe ngokuthe ngqo wokugqunyelelwa kwe-thermal kunye ne-anti-corrosion pipeline, ekubhekiselwa kuyo njengombhobho-in-pipe, ubhekiselele kumbhobho odibeneyo ogqunywe ngomaleko wokuchasana nokubola, umaleko wokugquma obushushu kunye nomgangatho wokucinezela. udonga lwangaphandle lombhobho wentsimbi.Ngokukodwa ezifanelekileyo kwiindawo ezinamaqondo aphezulu amanzi aphantsi komhlaba.Xa kuthelekiswa nemibhobho yokubeka imisele yemveli, inothotho lweenzuzo ezifana nokusebenza kakuhle kokugquma kwe-thermal, ukuchasana nomhlwa, ukusebenza kakuhle kokugquma, ubomi benkonzo ende, ulwakhiwo olulula kunye nofakelo, unyawo oluncinci, kunye neendleko zobunjineli eziphantsi.Isetyenziswe ngokubanzi kwindawo yokufudumeza, ukuthuthwa kwe-oyile, ishishini lemichiza, ifriji kunye neeprojekthi zokubonelela ngamanzi kwimimandla ye-alpine.
2. Ukufakwa kwe-phenolic foam
I-Phenolic foam insulation luhlobo lweplastiki enogwebu efunyenwe ngentlaka yephenolic enegwebu.Kukho iintlobo ezimbini zeerasi ezisetyenziselwa ukuveliswa kwe-phenolic foam: i-thermoplastic resin kunye ne-thermosetting resin.Ngenxa yokusebenza kakuhle kwenkqubo ye-thermosetting resin, i-foam ye-phenolic inokuveliswa ngokuqhubekayo, kwaye ukusebenza kwemveliso kungcono, ngoko ke izixhobo ze-phenolic foam zisebenzisa i-resin thermosetting.
3. Irabha ephucukileyo kunye neplastiki yokugquma
Irabha yodidi oluphezulu kunye neplastiki inefuthe elihle lokufakelwa kwe-thermal, kunye nobukhulu be-insulation esetyenziselwa umbhobho ofanayo kwipayipi ye-Shaanxi incinci, kwaye isixa sincinci;ngelo xesha, yinto edibeneyo yokufakelwa kwe-thermal, inkqubo ilula, kwaye inkqubela ikhawuleza;Ukongeza, irabha yodidi oluphezulu kunye neplastiki ziluhlaza, zinobuhlobo nokusingqongileyo, kwaye zicocekile.Izinto ze-insulation zinenkunkuma encinci ngexesha lokwakha kwaye azinabungozi kwimpilo.Irabha ephucukileyo kunye nokugqunyelelwa kweplastiki kuninzi kwaye kusetyenziswe ngokubanzi ngakumbi kwi-insulation yemibhobho yefriji kunye nemibhobho ye-condensate kwiinkqubo zefriji zomoya.
4. Ukufakwa kwe-polystyrene foam
Ukugqunywa kwegwebu lePolystyrene kunokwakheka kweeseli ezivaliweyo, ukufunxwa kwamanzi aphantsi, ukumelana nobushushu obuphantsi, kunye nokunganyibiliki kakuhle.Ngoko ke, isetyenziswe ngokubanzi kwizixhobo zefriji kunye nezixhobo zokugcina ezibandayo, ezifana nezikhenkcezisi, imigudu yomoya obandayo, ukugcinwa okubandayo, njl. Ukongeza, ngenxa yokuba i-polystyrene foam ayinayo ityhefu, ayinayo i-corrosion, encinci emanzini, ukukhanya emzimbeni. , ukugcinwa kobushushu, ukubumba ukubumba, kunye neasidi kunye nokumelana nokutyiwa kwealkali, ingasetyenziselwa ukugcina ubushushu bombhobho ngeenjongo ezahlukeneyo.
