Cov khoom ua kom sov txog 260 ° C thiab daim ntawv cog lus kom nruj kom qhov sib koom ua ke muaj zog dua cov yeeb nkab nws tus kheej.

1. Npaj cov khoom thiab cov cuab yeej

• Cov kav dej;
• haum;
• napkins;
• hnab looj tes;
• soldering hlau;
• yeeb nkab txiab;
• roulette;
• mem hluav;
• qib;
• isopropyl cawv.

2. Ua daim duab kos duab

Kev sib txuas ntawm cov kav dej polypropylene yog qhov yooj yim heev, tab sis - zoo li nrog rau lwm cov qauv - nws yog ib qho tsim nyog los npaj cov txheej txheem kev teeb tsa ua ntej pib ua haujlwm.

Daim duab kos rau ntawm daim ntawv kos duab nrog qhov chaw ntawm cov ntsiab lus khi, li qub thiab lwm yam tsim nyog. Yog li koj tuaj yeem kwv yees qhov ntev ntawm cov kav dej tam sim ntawd, nrog rau kev txiav txim siab qhov chaw, hom thiab tus naj npawb ntawm cov fittings xav tau.

Txij li thaum qhov kev sib txuas heats li ob qhov kawg ntawm cov kav dej, nws yog ib qho tseem ceeb rau kev yooj yim ntawm installation uas ib tug ntawm lawv tseem dawb. Qee cov kav dej nrog fittings tuaj yeem sib sau ua ke ntawm lub rooj, thiab tom qab ntawd muab tso rau hauv qhov chaw xav tau, ua ib qho sib koom ua ke. Tag nrho cov no yuav pab muab ib daim duab sib dhos.

3. Npaj cov hlau soldering

Feem ntau, cov cuab yeej raug hu ua "welding machine". Cov txheej txheem ntawm kev koom nrog polypropylene yuav siv qhov chaw yam tsis muaj kev siv solder, uas txhais tau hais tias nws yog vuam, tsis yog soldering. Peb yuav siv ob nqe lus.

Nruab nozzles ntawm txoj kab uas yuav tsum tau ntawm lub platform ntawm cov hlau soldering thiab kho lawv nrog ib tug ntsia hlau siv ib tug wrench. Yog tias koj ua haujlwm nrog cov kav dej ntawm ntau qhov ntau thiab tsawg - siv ob lub tes tsho ntxiv.

Teem lub cua sov rau 260 ° C thiab ntsaws rau hauv lub cuab yeej. Nws yuav siv sij hawm 10-20 feeb kom sov. Kev npaj rau kev ua haujlwm yuav raug qhia los ntawm LED qhov taw qhia. Koj yuav tsum tau tos lwm 5 feeb ua ntej welding thawj zaug.

Thaum polypropylene raug cua sov, cov pa phem thiab cov pa taws tawm, uas yog qhov zoo dua tsis txhob nqus pa. Yog li ntawd, ventilate chav tsev thaum ua haujlwm.

4. Ua tus cim

Thaum cov hlau soldering yog cua sov, npaj cov yeeb nkab thiab fittings. Rau kev vuam zoo, lawv yuav tsum nkag mus rau ib leeg nruj me ntsis rau qee qhov tob. Kev immersion tsis txaus yuav ua rau muaj kev sib txuas tsis zoo, thiab kev immersion ntau dhau yuav txo lossis tag nrho thaiv qhov chaw ntws nrog cov yas extruded. Nov yog cov txiaj ntsig tau pom zoo los ntawm cov tuam ntxhab feem ntau rau qhov ntau thiab tsawg:

Raws li koj tuaj yeem pom, qhov tob tob yog nyob ntawm txoj kab uas hla ntawm cov kav dej thiab fittings.

Txhawm rau kom tsis txhob ua yuam kev, ntsuas qhov ntev ntawm cov yeeb nkab, coj mus rau hauv tus lej nyiaj seam nyiaj thiab kos ib kab nrog xaum. Tom qab ntawd, ntawm qhov xav tau nyob deb ntawm lub cim no, kos lwm txoj kab - nws yuav ua qhov taw qhia siv thaum vuam.

Piv txwv li, peb yuav tsum tau txuas ib lub ces kaum thiab ib tug tee nyob rau hauv lub cua sov system. Qhov kev ncua deb ntawm lawv yog 270 mm. Rau fittings nrog ib txoj kab uas hla ntawm 25 hli, qhov tob ntawm soldering yog 18 hli, uas txhais tau hais tias peb ntxiv lwm 36 hli mus rau 270 (18 ntawm txhua sab). Raws li qhov tshwm sim, nws hloov tawm 306 hli - tsuas yog xws li cov yeeb nkab yuav tsum raug txiav tawm.

5. Txiav cov yeeb nkab

Rau kev txiav polypropylene, txiab tshwj xeeb yog siv, uas tseem hu ua yeeb nkab cutter. Lawv tso cai rau koj yooj yim txiav tawm cov yeeb nkab tuab tuab thiab tau txais cov npoo du, tsis muaj burr.

Teem lub txiab raws nraim perpendicular rau cov yeeb nkab thiab ua kom cov hniav nrog thawj lub cim. Thaum tuav cov yeeb nkab nrog ib txhais tes, nias lub txiab nrog rau lwm yam kom txog thaum ib feem raug txiav tag.

Nws yog ib qho tseem ceeb kom tau txais lub tiaj tus kawg kom cov yeeb nkab sib npaug nkag mus rau qhov haum thiab sib npaug sib npaug raws tag nrho txoj kab uas hla. Yog hais tias txiav obliquely, lub protruding ib feem yuav mus tob heev thiab cov molten polypropylene yuav tsum tau squeezed tawm, txo lub puab txoj kab uas hla ntawm lub haum.

Yog tias ntug tsis sib npaug thiab tso cai rau cov npoo, nws yog qhov zoo dua los txiav nws dua. Yog tias qhov ntev yog qhov kawg-rau-kawg, luas lub pob tw los ntawm kev tshem tawm tag nrho cov tshaj nrog ib rab riam ntse.

6. Degrease qhov chaw

Raws li cov lus qhia ntawm tag nrho cov manufacturers, qhov chaw yuav tsum tau welded yuav tsum tau degreased rau ib tug zoo kev twb kev txuas. Thiab txawm hais tias ntau tus neeg ua haujlwm tsis saib xyuas qhov no thiab txwv lawv tus kheej tsuas yog so cov kav dej nrog cov ntaub qhwv, peb pom zoo kom ua raws li cov thev naus laus zis.

Ntxuav txhua yam kab mob los ntawm cov kav dej. Tshem tawm cov dej uas seem thiab qhuav kom huv si nrog daim ntaub so ntswg los yog daim ntawv tso quav. Ntxuav qhov chaw ntawm fittings thiab kav dej nrog ib daim ntaub dampened nrog isopropyl cawv.

Nrog rau tib yam cawv, nws yog ib qho yooj yim los lwv tag nrho cov inscriptions ntawm cov kav dej thiab muab lawv ib tug zoo nkauj zoo nkauj.

7. Cov kav dej kub thiab haum

Muaj kev pheej hmoo ntawm kev kub nyhiab loj thaum ua haujlwm nrog cov hlau kub kub, yog li yuav tsum hnav cov hnab looj tes tiv thaiv. Qhov chaw ntawm ntau qhov ntau thiab tsawg yuav tsum tau ua kom sov rau qee lub sijhawm. Qhov loj ntawm txoj kab uas hla, qhov ntev.

Rau kev txhim kho kev sib txuas, nws yog ib qho tseem ceeb kom tsis txhob overheat polypropylene, txwv tsis pub cov khoom yuav ua kua, yaj thiab thaiv qhov haum ntawm sab hauv.

Ntxig qhov haum ua ntej, tom qab ntawd cov yeeb nkab rau hauv lub tes tsho ntawm cov hlau soldering. Thaum thawb cov khoom, tsis txhob tig lawv ncig lawv axis lossis qaij lawv. Ntxig cov yeeb nkab mus rau qhov tob uas tau teev tseg dhau los, kom txog thaum lub molten polypropylene ncav cuag cov xaum kab. Tsuas yog tom qab ntawd suav lub sijhawm faib.

Tag nrho cov ntaub ntawv qhia tau siv tau rau kev ua haujlwm ntawm qhov ntsuas kub ntawm 20 ° C. Yog tias chav tsev txias dua 5 ° C, lub sijhawm cua sov yog kwv yees li ob npaug.

8. Weld qhov sib koom ua ke

Tsis muaj tig los yog tilting, tshem tawm cov yeeb nkab los ntawm lub nozzles sai sai, thiab tom qab ntawd qhov haum, thiab txuas ob qho tib si nyob rau hauv qhov xav tau txoj hauj lwm txheeb ze rau ib leeg. Tsis txhob fuss, tab sis tsis txhob yig - koj muaj 4-6 vib nas this.

Tuav cov yeeb nkab thiab haum rau li 5 vib nas this kom ruaj ntseg sib koom ua ke. Lub sijhawm no, nws raug tso cai tig qhov kev sib txuas tsis tshaj 10 degrees los kho nws txoj haujlwm.

Lub sijhawm txias tag nrho, tom qab ntawd cov vuam tuaj yeem thauj khoom, yog 2 mus rau 4 feeb.

Nws yog ib qho yooj yim kom tshem tawm cov polypropylene seem ntawm lub nozzle nrog ib daim ntawv phuam thaum lub soldering hlau kub. Yog tias koj ntxuav lub tes tsho uas twb txias lawm, muaj kev pheej hmoo ntawm kev puas tsuaj rau Teflon txheej.

9. Tshawb xyuas qhov txuas

Koj tuaj yeem txiav txim siab qhov zoo ntawm qhov vuam los ntawm cov hlaws me me ntawm qhov kawg ntawm qhov haum. Yog hais tias nws tsis nyob ntawd, ces, tej zaum, qhov sib koom ua ke yog underheated thiab lub nruj yuav questionable. Yog hais tias lub influx loj heev, cov yeeb nkab feem ntau yuav overheated, thiab nws melted sab hauv, ib nrab thiab tag nrho thaiv qhov chaw ntws.

Rau cov neeg uas tab tom cuam tshuam nrog polypropylene vuam thawj zaug, nws yuav tsis yog superfluous rau thawj zaug xyaum thiab weld ob peb kev cob qhia pob qij txha. Nws yog qhov zoo dua los kawm txog kev sib txuas ncaj nraim. Tsis zoo li cov ces kaum thiab lwm yam zoo li cov fittings, lawv yooj yim los soj ntsuam zoo tom qab soldering, tsis tsuas yog los ntawm sab nraud, tab sis kuj los ntawm sab hauv.
