Hnub no, soldering tsis yog txoj kev sib txuas ntau tshaj plaws, tab sis nws tseem siv ntau zaus. Flux ib txwm siv rau qhov haujlwm no. Nws tuaj yeem ua tsis tau tsuas yog rosin nkaus xwb, tab sis kuj yog kev daws teeb meem raws li nws. Nws yog hais txog cawv-rosin flux.
Kev piav qhia
Ntawm no nws tsim nyog sau tseg tam sim ntawd tias cov tshuaj yog nruab nrab, tsis ua rau hlau corrosion. Nws tuaj yeem tso rau tom qab ua haujlwm.
Rosin nws tus kheej tau txais los ntawm kev txiav ntawm cov ntoo coniferous, tom qab ntawd tag nrho cov ntsiab lus tsis hloov pauv los ntawm cov muaj pes tsawg leeg tau evaporated. Cov seem nyob hauv kwv yees li 3/4 ntawm tag nrho cov khoom ntawm cov resin. Soldering rosin yeej ib txwm siv tom qab ua haujlwm ua ntej no.
Txhua yam yuav zoo txaus, yog tias tsis yog rau ib qho teeb meem loj. Tom qab muab cov hlau kub kub tso rau hauv cov dej ntws tawm, qhov chaw ua haujlwm ntawm cov hlau soldering tau npog nrog av thiab nyuaj rau kev ua haujlwm vim qhov pom tsis zoo.
Properties
Lub sijhawm dhau mus, nws tau pom tseeb tias kev siv kuarosin raws li ib tug flux yog ntau yooj yim dua. Vim lub xub ntiag ntawm ntuj acid-hom resin tshuaj, rosin tau txais cov khoom hauv qab no:
- zoo rau tshem tawm oxide ntawm hlau;
- kis tau zoo ntawm qhov chaw;
- npog tag nrho cov khoom sib koom ua ke.
Ethyl lossis cawv cawv tau ua thiab tseem siv los ua cov kuab tshuaj kom tau txais cov khoom sib xyaw. Yog li, ib qho cawv-rosin flux (SKF) tau txais. Muaj ob peb lwm cov kuab tshuaj organic uas rosin dissolves zoo - cov no yog acetone, benzene, roj av.
Txawm li cas los xij, niaj hnub no ethanol nquag siv rau cawv-rosin flux. Isopropyl cawv yog ze tshaj hauv cov khoom rau ethyl cawv. Txawm li cas los xij, kev siv cov tshuaj reagent no tsis tau nthuav dav, vim tias nws nyuaj dua kom tau txais, thiab qhov no tsuas yog ua tau los ntawm kev siv tshuaj lom neeg xwb.
GFR siv
Cawv-rosin flux tau siv sijhawm ntev thiab nquag heev. Nws tsis plam nws qhov cuam tshuam rau niaj hnub no, vim nws muab kev yooj yim ntawm kev siv thiab pom zoo ntawm cov ntsiab lus soldering.
Siv SKF tuaj yeem lav qhov nyiaj ncaj ncees rau ntau yam khoom siv, tab sis ua haujlwm zoo tshaj plaws nrog cov khoom siv tooj liab. Nrog kev pab ntawm cawv-rosin flux rau soldering, koj tuaj yeem ua haujlwm nrog xov tooj cua circuits thiab lwm yam boards. Nws lub ntsiab kom zoo dua nyob rau hauv cov ntaub ntawv no yog zoo spreadability. Qhov no tso cai rau cov flux nkag mus rau hauv qhov chaw nkag tsis tau tshaj plaws. Thaum ua hauj lwm nrog hom norosin thiab cov khoom siv qis-melting solder - melting point mus txog 330 degrees Celsius.
Tam sim no, koj tuaj yeem yooj yim yuav txhua yam khoom siv rau kev siv. Cawv-rosin flux (SKF) yog ib qho ntawm cov no. Ob lub tuam txhab hauv tsev thiab txawv teb chaws tau koom nrog hauv kev tsim khoom. Koj tuaj yeem yuav xws li flux npaj ua. Yog hais tias tus txheej txheem ua noj tsis tau ua txhaum cai thiab cov proportions tau pom, ces cov muaj pes tsawg leeg yuav ua tau raws li tag nrho cov kev cia siab. Txawm li cas los xij, koj tuaj yeem ua rau koj tus kheej.
Yuav ua li cas rau koj tus kheej flux
Soldering cawv-rosin flux tuaj yeem ua los ntawm tes. Qhov tseeb, txoj kev ua noj tsuas siv ob peb feeb xwb.
Ua ntej koj yuav tsum tau nqa cov resin thiab grind kom huv si. Qhov zoo dua qhov theem no tau ua tiav, qhov nrawm dua ntawm kev tawg ntawm txhua yam hauv cov kuab tshuaj yuav tshwm sim. Raws li qhov tshwm sim ntawm qhov ceev thiab me me manipulations, koj tuaj yeem tau txais cov tshuaj cawv-rosin rau soldering.
Koj tuaj yeem ua lwm txoj hauv kev. Ib daim ntawm resin yog qhwv hauv daim ntaub. Cellophane kuj tuaj yeem raug coj los siv rau lub hom phiaj no, txawm li cas los xij, cov kws paub txog vaj tse hauv tsev ceeb toom tias thaum lub sijhawm ua haujlwm hauv qab no nws tawg sai heev. Lub rosin yog li qhwv yog muab tso rau ntawm ib lub rooj thiab smashed mus rau ib tug hmoov nrog ib tug rauj. Cov kws paub txog ntau tshaj plaws tau hloov kho los siv cov nqaij grinder zoo tib yam rau lub hom phiaj no.
Lwm tus ua-nws-koj tus kheej siv tus pin dov lossis lub raj mis tuab es tsis txhob siv rauj los yob tawm ib daim rosin.
Txhua txoj kev nosib sau ua ke tib lub hom phiaj - nws yog ib qho tsim nyog yuav tau zom cov khoom noj rau lub xeev hmoov.
Kev daws teeb meem
Tom qab ntawd, qhov tshwm sim ntawm cov hmoov yuav tsum tau nchuav rau hauv lub raj mis, vial, vial lossis lwm lub thawv me me. Ntau tus neeg siv cov ntsia thawv polish ntim. Ntawm no nws yog ib qho tseem ceeb heev kom tau txais lub hang ntawm pouring tawm cov hmoov av nyob rau hauv xws li ib tug txoj kev uas nws tsis crumble, koj yuav tsum tau ua tib zoo thiab meej ncuav hmoov. Tom qab ntawd, haus cawv tuaj yeem muab ntxiv rau tib lub vial.
Raws li qhov piv, qhov pom zoo piv yog 2: 3 (kua rau hmoov).
Yog tias koj xav tau cov flux nrog cov viscosity siab dua, koj tuaj yeem ua kom cov resin nce ntxiv, thiab tso cov cawv tib yam. Nws yog ib qho tsim nyog sau cia tias txhua tus tswv tsev muaj peev xwm ua tau zoo, tom qab ob peb zaug, ntawm nws tus kheej xaiv qhov sib piv uas haum rau nws txoj haujlwm, rau cov ntu uas nws cuam tshuam.
Nws puas tuaj yeem hloov cawv?
Qee tus kws paub txog kev ua haujlwm hais tias cawv tuaj yeem cawm tau, yog tias tsim nyog, thiab hloov nrog cov cologne pheej yig. Qhov tseeb, qhov kev pom zoo no muaj teeb meem heev. Qhov tsis hnov tsw yuav, ntawm chav kawm, yuav qab ntxiag dua, tab sis cov khoom ntxiv tuaj yeem ua rau lwj lossis ua rau cov khoom zoo.
Lwm tus tham txog kev siv vodka. Ntawm no, ib yam nkaus, nws yog qhov tsis sib haum xeeb, vim tias rosin yog cov organic compound, thiab yog li nws tsis yaj zoo hauv dej. Vodka yog sib xyaw ntawm cawv thiab dej. Dissolve resinTxawm nyob rau hauv high-zoo vodka nws yuav nyuaj heev.

Cov ntaub ntawv xa tuaj: tus kheej xaj, daim ntawv them nqi, daim ntawv xaj, cov ntaub ntawv xa khoom thiab cov chaw xa khoom xa tuaj
Kev ua haujlwm hauv kev xa khoom yog nrov heev niaj hnub no, tshwj xeeb tshaj yog cov tub ntxhais hluas muaj siab nyiam. Tus neeg xa xov tsis yog ib tus neeg xa khoom xwb, tab sis yog tus kws tshaj lij uas muaj kev txawj ntse thiab tuaj yeem nqa parcel los yog xa mus rau qhov chaw nyob uas tau teev tseg nrog cov khoom zoo thiab sai
Cov cai rau kev sau daim ntawv pov thawj 2 tus kheej cov nyiaj tau los se: cov lus qhia ib kauj ruam, cov ntawv xav tau, hnub kawg thiab cov txheej txheem xa khoom
Cov tib neeg yuav tsum tau hloov cov se tau los ntawm lawv cov nyiaj tau los rau hauv cov peev nyiaj hauv xeev. Ua li no, daim ntawv pov thawj ntawm 2 tus kheej cov nyiaj tau los ua se tau ua tiav. Cov ntaub ntawv no qhia txog cov nyiaj tau los thiab kev txiav se tawm ntawm cov tib neeg. Tus tswv ntiav haujlwm yuav tsum xa cov ntaub ntawv no txhua xyoo mus rau cov kev tswj xyuas muaj feem cuam tshuam ntawm qhov chaw sau npe. Cov lus qhia thiab cov cai rau kev sau daim ntawv pov thawj 2 ntawm cov nyiaj tau los ntawm tus kheej yuav raug tham hauv kab lus
Ethyl cawv rectified. Ethyl cawv - daim ntawv thov. Ethyl cawv ntau lawm
Nws tsis yog ib qho zais cia uas tau kho ethyl cawv yog siv los ua cov khoom siv tseem ceeb rau kev tsim cov khoom vodka. Qhov no yog ib qho khoom tseem ceeb hauv cheeb tsam no. Xav paub ntxiv txog qhov no tom qab
Daim ntawv thov nyiaj rov qab ntawm cov nyiaj tau los ntawm tus kheej rau kev kawm: thaum koj tuaj yeem tau txais nws, cov cai rau kev thov rau kev txiav se tawm
Tau txais kev txiav se tawm hauv Russia yog txheej txheem yooj yim heev. Kab lus no yuav qhia rau koj txhua tus hais txog yuav ua li cas kom tau txais cov nqi kawm ntawv txiav tawm thiab thov kom rov qab tau cov nyiaj tau los
Flux rau vuam: lub hom phiaj, hom vuam, flux muaj pes tsawg leeg, cov cai ntawm kev siv, GOST cov cai, qhov zoo thiab qhov tsis zoo ntawm daim ntawv thov
Qhov zoo ntawm cov vuam yog txiav txim siab tsis yog los ntawm lub peev xwm ntawm tus tswv los npaj lub arc kom raug, tab sis kuj los ntawm kev tiv thaiv tshwj xeeb ntawm thaj chaw ua haujlwm los ntawm kev cuam tshuam sab nraud. Tus yeeb ncuab tseem ceeb ntawm txoj hauv kev los tsim kom muaj kev sib txuas ntawm cov hlau uas muaj zog thiab ruaj khov yog cov huab cua puag ncig ntuj. Lub vuam yog cais tawm los ntawm cov pa oxygen los ntawm cov flux rau vuam, tab sis qhov no tsis yog nws txoj haujlwm xwb
