Bhodhoro regiraziKuputira chinhu chakakosha pakurapa pamusoro pechiso mubasa rekurongedza zvizoro. Kunowedzera jira rakanaka mumudziyo wegirazi. Munyaya ino, tinogovana chinyorwa pamusoro pekurapa pamusoro pebhodhoro regirazi uye hunyanzvi hwekufananidza mavara.
Ⅰ, hunyanzvi hwekugadzira pendi yebhodhoro regirazi
1. Shandisa mvura yakachena kana kuti mvura kuti ugadzirise pendi kuti ive viscosity yakakodzera yekupfapfaidza. Mushure mekuyera neTu-4 viscometer, viscosity yakakodzera inowanzova masekondi 18 kusvika 30. Kana pasina viscometer parizvino, unogona kushandisa nzira yekuona: kumutsa pendi netsvimbo (simbi kana tsvimbo yehuni) wobva waisimudza kusvika pakakwirira kwe20 cm woimisa kuti uone. Kana pendi ikasapwanyika munguva pfupi (masekondi mashoma), inenge yakakora zvakanyanya; kana ikapwanyika pakarepo painobuda pamucheto wepamusoro webhaketi, inenge yakatetepa zvakanyanya; kana ikamira pakukwirira kwe20 cm, pendi inenge yakatwasuka uye inomira kuyerera uye inodonha nekukasira. Viscosity iyi ndiyo yakakodzera.
2. Kumanikidzwa kwemhepo kunofanira kudzorwa pa 0.3-0.4 MPa (3-4 kgf/cm2). Kana kumanikidzwa kwakaderera, mvura yependi haizogadziriswa zvakanaka uye maburi achaumbwa pamusoro; kana kumanikidzwa kwacho kwakanyanya, kuchadonha zviri nyore uye mhute yependi ichave yakakura zvakanyanya, izvo zvinoparadza zvinhu uye zvinokanganisa hutano hwemushandisi.
3. Kureba pakati pemuromo wemuchina nepamusoro kazhinji i200-300 mm. Kana iri pedyo zvakanyanya, inodonha zviri nyore; kana iri kure zvakanyanya, mhute yependi inenge isina kuenzana uye maburi achaonekwa zviri nyore, uye kana muromo wemuchina uri kure nepamusoro, mhute yependi ichabhururuka ichienda, zvichikonzera marara. Saizi chaiyo yepakati inofanira kugadziriswa zvakakodzera zvichienderana nerudzi, viscosity uye kumanikidzwa kwemhepo kwependi yebhodhoro regirazi. Nguva yekupfapfaidza pendi inoomesa zvishoma nezvishoma inogona kuva kure, uye inogona kuva kure kana viscosity iri diki; kana kumanikidzwa kwemhepo kwakakwira, nguva yacho inogona kuva kure, uye inogona kuva pedyo kana kumanikidzwa kuri kudiki; iyo inonzi closer nefar zvinoreva nzvimbo yekugadzirisa iri pakati pe10 mm ne50 mm. Kana ikapfuura iyi nzvimbo, zvakaoma kuwana firimu rependi rakakodzera.
4. Pfuti yekupfapfaidza inogona kufambiswa kumusoro nekudzika, kuruboshwe nekurudyi, zviri nani nekumhanya kwakafanana kwe10-12 m/min. Nozzle inofanira kupfapfaidzwa yakatsetseka pamusoro pechinhu, uye kupfapfaidza kwakaonda kunofanira kuderedzwa. Pakupfapfaidza kumativi ese epamusoro, ruoko rwakabata chinopfupfaidza pfuti runofanira kusunungurwa nekukurumidza kuderedza mhute yependi, nekuti mativi maviri epamusoro pechinhu anowanzo gamuchira kupfapfaidza kunopfuura kaviri, uye ndidzo nzvimbo dzinogona kudonha mvura.
5. Pakupfapfaidza, chikamu chinotevera chinofanira kudzvanya 1/3 kana 1/4 yechikamu chekare, kuitira kuti pasave nekubuda mvura. Pakupfapfaidza pendi inoomesa nekukurumidza, zvakakosha kupfapfaidza zvakarongeka panguva imwe chete. Mhedzisiro yekupfapfaidza zvakare haina kunaka.
6. Pakupfapfaidza munzvimbo yakashama panze, teererai nzira yemhepo (hazvina kukodzera kushanda mumhepo ine simba), uye mushandi anofanira kumira akananga kumhepo kudzivirira kuti mhute yependi isaputirwe pafirimu rependi rakapfapfaidzwa zvokonzera granular surface inonyadzisa.
7. Kurongeka kwekupfapfaidza ndekwekuti: kwakaoma kutanga, nyore gare gare, mukati kutanga, kunze gare gare. Kumusoro kutanga, pasi gare gare, nzvimbo diki kutanga, nzvimbo hombe gare gare. Nenzira iyi, mhute yependi inopfapfaidzwa gare gare haizopfapfaidzi pafirimu rependi rakapfapfaidzwa uye haizokuvadzi firimu rependi rakapfapfaidzwa.
Ⅱ、Unyanzvi hwekufananidza ruvara rwependi yebhodhoro regirazi
1. Nheyo huru yeruvara
Tsvuku + yero = orenji
Dzvuku + bhuruu = pepuru
Yero + pepuru = girini
2. Nheyo huru yemavara anoenderana
Dzvuku negirini zvinopindirana, kureva kuti, dzvuku rinogona kuderedza girini, uye girini rinogona kuderedza tsvuku;
Yero nepepuru zvinopindirana, kureva kuti, yero inogona kuderedza pepuru, uye pepuru inogona kuderedza yero;
Bhuruu neorenji zvinopindirana, kureva kuti, bhuruu rinogona kuderedza orenji, uye orenji rinogona kuderedza bhuruu;
3. Ruzivo rwekutanga rwemavara
Kazhinji, ruvara rwunotaurwa nevanhu rwakakamurwa kuita zvinhu zvitatu: ruvara, kupenya uye kuzara. Ruvara runonziwo ruvara, kureva rutsvuku, orenji, yero, girini, cyan, bhuruu, pepuru, nezvimwewo; kupenya kunonziwo kupenya, kunotsanangura kupenya nerima reruvara; kuzara kunonziwo chroma, kunotsanangura kudzika kweruvara.
4. Nheyo huru dzekufananidza mavara
Kazhinji, usashandise marudzi anopfuura matatu ependi kuti uenzanise mavara. Kusanganisa tsvuku, yero nebhuruu mune imwe chikamu kunogona kuwana mavara akasiyana-siyana (kureva mavara ane mavara akasiyana). Zvichibva pamavara ekutanga, kuwedzera chena kunogona kuwana mavara ane mavara akasiyana (kureva mavara ane mavara akasiyana). Zvichibva pamavara ekutanga, kuwedzera dema kunogona kuwana mavara ane chiedza chakasiyana (kureva mavara ane kupenya kwakasiyana).
5. Maitiro ekutanga ekufananidza mavara
Kusanganisa nekufananidza pendi kunotevera musimboti wekubvisa mavara. Mavara matatu makuru itsvuku, yero nebhuruu, uye mavara awo anowirirana igirini, pepuru neorenji. Mavara anonzi anowirirana mavara maviri echiedza akasanganiswa muchikamu chakati kuti awane chiedza chichena. Ruvara rwakabatana rwetsvuku igirini, ruvara rwakabatana rweyero ipepuru, uye ruvara rwakabatana rwebhuruu iorenji. Kureva kuti, kana ruvara rwakanyanya kutsvuka, unogona kuwedzera girini; kana rwakanyanya kutsvuka, unogona kuwedzera pepuru; kana rwakanyanya kusviba, unogona kuwedzera orenji. Mavara matatu makuru itsvuku, yero, nebhuruu, uye mavara avo anowirirana igirini, pepuru, neorenji. Mavara anonzi anowirirana mavara maviri echiedza akasanganiswa muchikamu chakati kuti awane chiedza chichena. Ruvara rwakabatana rwetsvuku igirini, ruvara rwakabatana rweyero ipepuru, uye ruvara rwakabatana rwebhuruu iorenji. Kureva kuti, kana ruvara rwakanyanya kutsvuka, unogona kuwedzera girini; kana rwakanyanya kutsvuka, unogona kuwedzera pepuru; kana rwakanyanya kusviba, unogona kuwedzera orenji.
Usati wafananidza mavara, tanga waona nzvimbo yeruvara runofanira kuenzaniswa zvichienderana nemufananidzo uri pazasi, wobva wasarudza mavara maviri akafanana kuti aenzane nechikamu chakati. Shandisa bhodhi rebhodhoro regirazi rimwe chete kana chidimbu chebasa chinofanira kupfapfaidzwa kuti chienderane neruvara (ukobvu hwe substrate, bhodhoro regirazi remunyu wesodium uye bhodhoro regirazi remunyu wecalcium zvicharatidza mhedzisiro dzakasiyana). Paunenge uchifananidza ruvara, tanga wawedzera ruvara rukuru, wobva washandisa ruvara rwakasimba seruvara rwechipiri, wedzera zvishoma nezvishoma uye nguva nenguva uchikurunga, uye tarisa shanduko dzeruvara chero nguva, tora mienzaniso woipukuta, kukwesha, kupfapfaidza kana kuinyika pamuenzaniso wakachena, uye enzanisa ruvara nemuenzaniso wekutanga mushure mekunge ruvara rwagadzikana. Nheyo yekuti "kubva pachiedza kusvika parima" inofanira kunzwisiswa mukuita kwese kwekufananidza mavara.
