1.Qhov kev tshuaj xyuas thiab kev npaj ua ntej kev kho mob yog dab tsi?
Txiav txim siab qhov ua rau warping:
Teeb meem kev teeb tsa: xoob screws, kho qhov sib nrug loj heev, cov pob qij txha tsis sib haum.
Cov ntaub ntawv aging: xeb ntawm steel daim hlau, shrinkage ntawm cov ntaub ntawv tseem ceeb, tawg ntawm coatings.
Sab nraud quab yuam: rub los ntawm cov cua muaj zog, deformation vim kev cuam tshuam, thiab kev ntxhov siab concentration tshwm sim los ntawm thermal expansion thiab contraction.
2.Yuav ua li cas nrog me ntsis warping?
Ntxuav cov plua plav, xeb, thiab cov hnub nyoog sealant los ntawm qhov chaw tsa, thiab siv cov ntawv xuab zeb los txhuam cov hlau phaj kom txog thaum nws du.
Kho cov npoo tsa, thiab rov- nruab nws tus kheej-tapping screws ze ntawm qhov qub kho cov ntsiab lus. Cov ntsia hlau yuav tsum tau them nrog roj hmab gaskets thiab nruj kom txog thaum lub phaj steel haum rau lub hauv paus.
Siv cov sealant raws cov pob qij txha, sib cog lus thiab txhuam kom tiaj tus kom ntseeg tau tias cov nplaum nplaum tag npog qhov khoob, thiab tsis txhob los nag hauv 24 teev.
3.Yuav ua li cas rau nruab nrab warping?
Yog hais tias lub phaj steel yog warped vim deformation, thawj zaug siv ib tug roj hmab rauj maj mam kais lub deformed ib feem thiab sim rov qab los rau flatness (tsis txhob muaj zog ntau dhau thiab ua rau tawg).
Tshem tawm cov qub xoob screws thiab ntxiv cov ntsiab lus kho nyob rau hauv qhov chaw deformed (qhov sib nrug yog tswj ntawm 30-50cm, uas yog denser tshaj qhov sib nrug). Cov ntsia hlau yuav tsum nkag mus rau lub phaj steel thiab lub hauv paus keel kom ruaj khov.
Rau cov vaj huam sib luag, yog tias cov khoom siv tseem ceeb (xws li pob zeb wool, polystyrene) shrinks vim dej nkag los yog kev laus, cov khoom tseem ceeb ntawm qhov tsis sib haum xeeb yuav tsum tau txiav tawm, ntim nrog cov khoom siv tshiab, thiab npog nrog lub phaj hlau ntawm cov khoom qub, kho nrog rivets nyob ib ncig ntawm qhov chaw (sib nrug 10.-15cm), thiab tom qab ntawd muab khi nrog cov rivets.
4.Yuav ua li cas nrog kev sib ntaus sib tua hnyav?
Tshem tawm cov xim hlau daim hlau uas yog warped thiab puas nyob ib ncig ntawm (ua tib zoo saib rau txoj hauj lwm ntawm kev kho screws kom tsis txhob ua puas rau cov daim hlau uas nyob ib sab).
Xyuas seb lub hauv paus keel puas yog xeb los yog xoob. Yog tias muaj teeb meem, kho nws ua ntej (hloov lub pob txha rusted thiab ntxiv dag zog rau cov pob txha xoob).
Txhim kho cov xim hlau phaj tshiab, xyuas kom meej tias qhov sib tshooj ntev nrog cov ntawv uas nyob ib sab yog ntau dua lossis sib npaug li 10cm (kev sib tshooj ntawm cov cua kev taw qhia yog dej tsis zoo), qhov sib nrug ntawm kev kho cov ntsia hlau yog 20-30cm, thiab cov npoo thiab cov pob qij txha raug kaw nrog sealant. Yog tias tsim nyog, ntxiv ib qho kev txhawb nqa keel hauv qab phaj los txhim kho kev ruaj ntseg.
5.Dab tsi yuav tsum tau ceev faj tshwj xeeb?
Warping ntawm cov xim hlau phaj ntawm lub ru tsev: Nws yog ib qho tsim nyog los ua haujlwm hauv huab cua tsis muaj cua, thiab khi txoj hlua ruaj ntseg thaum ua haujlwm kom tsis txhob poob. Yog hais tias nws yog tshwm sim los ntawm typhoon los yog muaj zog cua, nws yog tsim nyog los xyuas seb lub zuag qhia tag nrho cov qauv yog ruaj khov kom tsis txhob muaj lwm yam kev puas tsuaj. Kev kho cov ntsia hlau yuav tsum tilted 5℃-10℃mus rau lub ridge los txhim kho cua tsis kam.
Warping ntawm cov xim hlau phaj ntawm phab ntsa: Yog tias nws nyob ze rau hauv av, nws yog ib qho tsim nyog los xyuas seb nws puas yog tshwm sim los ntawm kev sib haum xeeb hauv av, thiab kho cov kev txhawb nqa hauv qab yog tias tsim nyog. Lub sealant ntawm qhov sib koom ua ke yuav tsum xaiv huab cua - cov khoom tiv thaiv (xws li silicone kua nplaum) kom tsis txhob muaj kev laus thiab tawg los ntawm tshav ntuj ncaj qha.
Warping tshwm sim los ntawm xeb: Nws yog ib qho tsim nyog yuav tsum tau tshem tawm cov xeb ua ntej (nrog cov ntawv xuab zeb lossis xeb tshem tawm), siv cov tshuaj tiv thaiv- xeb tom qab nthuav tawm cov xim qub ntawm cov hlau, thiab tom qab ntawd kho thiab kaw nws kom tiv thaiv kev sib kis ntawm xeb.
