Ngemibhobho umbala Area - ingakumbi itafile kunye neziphakamiso

ngemibhobho Paint inkqubo inyanzelekile, nto leyo lidlala indima nje yobuhle, kodwa lwenze ubomi mome. umsebenzi yokupeyinta eyenziwa njengamanzi primer kunye nepeyinti. Kodwa ukuba njani indlela bona kufuneka yaye ngokwaneleyo, kwaye intsalela usele? Kunzima kakhulu ukwenza oku xa becwangcisa isixa esikhulu umsebenzi, umzekelo, inkqubo yonxibelelwano kwisikhululo lonikezelo. Ukuze ngokufanelekileyo ukubala ubungakanani ipeyinti kufuneka wazi indawo umbala yombhobho. Ukuze ufunde ukubala njani, siza kuthetha ngakumbi.

imihlobo yemibhobho

Okokuqala, kufanele kuqatshelwe ekusetyenzisweni yokupeyinta iza azachaphazela kuphela ubungakanani imibhobho, kodwa imilo kunye nesakhiwo umbandela ukusuka apho kwenziwa. Umzekelo, enamathela yemveliso anencasa incence ezilinganayo uya kufuna izixa ezahlukeneyo Coatings.

Imibhobho unokuba imilo ezahlukeneyo kakhulu kunye nesayizi candelo. Kuxhomekeka ngezi parameters, kumiselwa umda kunye nokusebenza kweemveliso umbhobho. Lolona hlobo luqhelekileyo kweetyhubhu zezindlu kunye setyhula cross-candelo, amaxesha amaninzi isetyenziselwa ukwakhiwa kwemibhobho kunye imibhobho negesi.

A oluthandwa yenkcenkce yokwakha ke umbhobho agciniweyo ukuba icandelo cross ngaphandle setyhula. Bayakwazi ibe mbhoxo, isikwere kunye uxande. Phakathi kwazo zizakhelo izakhiwo, izakhiwo ezahlukeneyo zesinyithi, imigangatho kunye nobude.

tube incence kunye necandelo cross ngeenxa zisetyenziselwa ukwakha inkqubo pressureless komhlaba zasekhaya kunye zoshishino kwelindle, amanzi amdaka uqhwithela.

Kukho kwakhona tube cone-ezimise. Le misebenzi yenzelwe ukuba iinkqubo pressurization.

walinganisa

Ukubala ubungakanani izinto ipeyinti ngeendlela ezimbini: usebenzisa itafile ekhethekileyo okanye usebenzisa ifomula yemigca. Yaye eneneni, yaye kwelinye icala, kufuneka wenze imilinganiselo ezichanekileyo imveliso.

Ukuba kukho itafile imibala imibhobho isikwere, sifuna ukufumana kuphela kulo indawo kunye mbini iparameters efanayo njengoko zifumaneka imilinganiselo, kunye nokusetyenziswa inki imbono okanye primer. Calculation usebenzisa ifomula - ezinobunzima, kodwa akukho ndlela ngaphantsi esebenzayo. Ukuze ubone umbhobho indawo umbala imilo ethile kunye necandelo umnqamlezo, ifomula efanelekileyo.

ngemibhobho zezindlu

Ukwenza izibalo, kuyimfuneko ukwazi ubude umbhobho kunye radius sayo. Ubude ulinganiswa eemitha, kunye noluhlu - in iimilimitha. Sebenzisa le ndlela ilandelayo:

S = 2 x π * R x L, apho:

• S - umbhobho indawo ziipeyintiwe;
• π - pi lingana 3.14;
• R - radius;
• L - ubude.

Ngokomzekelo, xa ubude ityhubhu kwe-10 m kunye ububanzi-60 mm, indawo yayo umphezulu bekuya kuba 1,88 macala onke. m.

Le equation efanayo ibalwa, kunye nemibhobho umjelo indawo imibala. Umahluko kuphela phakathi kwezi izakhiwo ezinkulu. Ngokomzekelo, xa amaqula ilindle ubukhulu inokuba 70-200 cm Kwiimeko ezinjalo, isiseko kubude eqhelekileyo ezi mveliso -. 90 cm.

Indawo yabucala pipe imibala

Ukuze kufunyaniswe ixabiso umdla kuyimfuneko ukwazi:

• uthambekise elinye icala umbhobho (H);
• ukuphakama kwelinye icala (W);
• ubude (L).

Izibalo ezenziwe usebenzisa ifomula ilandelayo: S = 2 x H x L + 2 x W x L. Ngokomzekelo, xa ubude ezindulini-10 m kunye namacala - cm 10 no-5, indawo ekufuneka wawutyabeka bekuya kuba 3 macala onke. metres.

Imibhobho ephakathi yentsimbi Square imibala etsobhileyo

Xa imibhobho kunye namanyathelo cone thumbanails imida zilandelayo:

• ubude (L);
• ububanzi wesangqa ezincinci (R1);
• ububanzi wesangqa enkulu (R2).

Ukuze ubone isithuba umbala isicelo imibhobho ifomula S = 2 x π x R1 x L + π x (R1 x R1 + R2 x R2). Umzekelo, ukuba ubude yoyilo iya kuba-10 m, kanti ke radii ayalingana 3 no-6 cm, le ndawo imalunga 2 eemitha.

imibhobho yenyuka

Xa iimveliso ezifana kakhulu kunzima ukubala ngokuchanekileyo kwindawo umphezulu, ngenxa yokuba angaqwengwa ecaleni ubude. Kuba lula ukubala, onke amaxabiso afunyenwe imilinganiselo, uyacebiswa ukuba akhuphe ngokubhala ngokohlobo itafile.

Ngenxa yoko, kukho imfuneko yokuba kumiselwe imida zilandelayo:

• engaba esime (A);
• iindawo kwelivi ncwaba ubude ubukhulu (B, D);
• corrugations ubungakanani inyathelo (C);
• angle isabelo smooth (E);
• ukuphakama wesahlulo incence (F);
• Product ngokukrwela umgca (G).

Xa umzekelo ethile, cinga Ukubala iqhutywa njani. Umzekelo, ixabiso A ilingana 3 mm. Ukuze ubone ubungakanani inxalenye ahanjiswa ye kwifomula 2 x π x A isetyenziswa Ngaloo ndlela, a 18,84 mm. kufuneka liphindwe ixabiso D, makube ilingana no-20 mm. Ngokusekelwe kwiinkcukacha ngasentla, umntu ukufumanisa ubude corrugations kwifomu sesa - 38,84 mm.

Ukususa ukuthambeka, ixabiso nibale E. Eli nani iya kulingana kabini ubukhulu, ngamanye 12 mm.

Ukucinga ukuba ubude imveliso-10 m. Ukuze ukubala inani ezibayeni, ubude bahlulwe inyathelo 866 kwaye afumane izinto. Okulandelayo, amisele ubude ityhubhu incence zikwimeko nangengalo. Xa ububanzi of, umz, 52 mm, ummandla iyonke yokwakha 54,92 macala onke. m.

Choice of odweba

Imibhobho esetyenziselwa ukupeyinta iintlobo ezahlukeneyo ipeyinti:

• wayesebenzisa acrylic, aba bakhoyo apha ukwakheka nenezinyibilikisi, ngokubonelela ekugqibeleni owomeleleyo elide isilungiseleli seglosi.
• wayesebenzisa Alkyd thaca ezithengiswayo kuluhlu olubanzi imibala. inks ezinjalo linophawu iyahlala, benza umaleko ethembekileyo akuthethi ukuzivula kwaye luphele.
• Water-dispersive paint. Izinto eziluncedo ze ezinjalo ezaqanjwa ziquka ukukwazi okusula ngokukhawuleza kunye nokungabikho malodor. Ilishwa - ukuxhathisa engentlanga lingonakali kunye namanzi. Ngaphambi kokuba usebenzise inks of nokusasazeka yamanzi-based umbhobho ukuba camera arhente Priming.
• Ipeyinti Oil. Kuba imibhobho ukupeyinta esetyenziswa enqabile. Ifumaneka uluhlu umbala encinane. Phambi ukupeyinta imiphezulu yesinyithi, kuqukwa imibhobho, kufuneka isicelo se primer, nto leyo ukunika ulwalamano oluhle kunye ipeyinti. Umbala Ukwakhiwa ngenxa yeoli lisetyenziswe primer womisa iimaleko ubuncinane ezimbini.

Xa ukhetha uhlobo lwepeyinti ukuba imibala inqawe kuyimfuneko, kuqala kwiinto zonke, ukuba, ingqalelo iimeko zabo injongo kunye yokusebenza, njengoko izinto ezifana lobushushu, ukufuma, umngcipheko umonakalo ngomatshini, njl, iya kuxhomekeka kwindlela ayasiqinisekisa ipeyinti, kwaye ithuba imibhobho inkonzo ngokwabo.
