Kuputira bhodhoro regirazi, munyaya yekurongedza zvinhu zvekushongedza, ichi chinhu chakakosha pakurapa pamusoro, anowedzera runako mumudziyo wegirazi, muchinyorwa chino, tinogovana chinyorwa pamusoro pekurapa pamusoro pebhodhoro regirazi uye hunyanzvi hwekufananidza mavara mupasuru yemuraraungu yeShanghai.
一,
Unyanzvi hwekugadzira pendi yebhodhoro regirazi
1. Shandisa mvura yakachena kana kuti mvura kuti ugadzirise pendi kuti ive viscosity yakakodzera yekupfapfaidza. Viscosity yakakodzera inowanzova masekondi 18 kusvika 30 sezvinoyerwa neTu-4 viscometer. Kana pasina viscometer kwenguva yakati, nzira yekuona inogona kushandiswa: kumutsa pendi netsvimbo (simbi kana tsvimbo yehuni) woisimudza kusvika pakakwirira pe20 cm kuti urege kuiona. Yakakora zvakanyanya; kana tambo ikatyoka pakarepo painobuda pamucheto wepamusoro webharero, inenge yakatetepa zvakanyanya; painomira pakakwirira pe20 cm, mvura yependi inoumba mutsetse wakatwasuka, uye kuyerera kwayo kunomira ipapo ipapo uye kunodonha. Viscosity iyi ndiyo yakakodzera.
2. Kumanikidzwa kwemhepo kunonyatsodzorwa pa 0.3-0.4 MPa (3-4 kgf/cm2). Kana kumanikidzwa kwakaderera, mvura yependi inenge isina atomu yakakwana, uye maburi achaumbwa pamusoro; kana kumanikidzwa kwacho kwakanyanya, kuchadonha zviri nyore, uye mhute yependi ichave yakakura zvakanyanya, izvo zvisingangoparadzi zvinhu chete, asiwo zvinokanganisa hutano hwemushandisi.
3. Nguva iri pakati pemuromo wechinhu nepamusoro pechinhu inowanzova 200-300 mm. Kana iri pedyo zvakanyanya, zviri nyore kudonha; kure zvakanyanya, mhute yependi haina kuenzana uye inowanzo donha, uye mhute yependi yakapararira munzira kubva pamuromo wechinhu kure nepamusoro pechinhu, zvichikonzera marara. Saizi chaiyo yepakati inofanira kugadziriswa nemazvozvichienderana nerudzi rwependi yebhodhoro regirazi, viscosity uye kumanikidzwa kwemhepo. Nguva yekupfapfaidza pendi inoomesa zvishoma nezvishoma inogona kuva kure, kana viscosity iri diki, inogona kuva kure; kana kumanikidzwa kwemhepo kwakakwira, nguva yacho inogona kuva kure, uye kumanikidzwa kunogona kuva kudiki kana kumanikidzwa kuri kudiki; Kana ikapfuura iyi nhanho, zvinova zvakaoma kuwana firimu rependi rakakodzera.
4. Pfuti yekupfapfaidza inogona kufambiswa kumusoro nekudzika, kuruboshwe nekurudyi, zviri nani nekumhanya kwe10-12 m/min, uye muromo wemuromo unofanirwa kupfapfaidzwa pamusoro pechinhu kuti kuderedze kupfapfaidza kwakakombama. Pakupfapfaidza kumativi ese echinhu, ruoko runodhonza trigger yepfuti yekupfapfaidza runofanira kusunungurwa nekukurumidza kuderedza mhute yependi. Nekuti mativi maviri echinhu anowanzo fanirwa kupfapfaidzwa kanopfuura kaviri, ndiyo nzvimbo inonyanya kukonzera kudzika.
5. Pakupfapfaidza, pfupa rinotevera rinofanira kudzvanywa pachikamu chimwe chete kubva muzvitatu kana chikamu chimwe chete kubva muzvina chepfupa rapfuura, kuitira kuti pasave nekubuda kwepfupa. Pakupfapfaidza pendi inoomesa nekukurumidza, pfapfaidza zvakatevedzana panguva imwe chete. Mhedzisiro yekupfapfaidza haina kunaka.
6. Pakupfapfaidza munzvimbo yakashama, teererai nzira yemhepo (musashande kana mhepo yaoma), uye mushandi anofanira kumira munzira yemhepo kuti adzivise mhute yependi kuti isafurirwe nemhepo ichienda kufirimu rependi rakapfapfaidzwa zvokonzera granular surface inonyadzisa.
7. Kurongeka kwekupfapfaidza ndekwekuti: kutanga kwakaoma uye kwozove nyore, kutanga mukati uye kwozove kunze. Kutanga kwakakwirira, kwozove pasi, kutanga nzvimbo diki uye kwozove nzvimbo yakakura. Nenzira iyi, mhute yependi yakapfapfaidzwa haizopfapfaidzi pafirimu rependi yakapfapfaidzwa uye kukuvadza firimu rependi yakapfapfaidzwa.

Unyanzvi hwekufananidza mavara ependi yebhodhoro regirazi
1. Nheyo huru yekupfava
tsvuku + yero = orenji
tsvuku + bhuruu = pepuru
yero + pepuru = girini
2. Nheyo huru yemavara anoenderana
Tsvuku negirini zvinopindirana, kureva kuti, tsvuku inogona kuderedza girini, uye girini inogona kuderedza tsvuku;
Yero nepepuru zvinopindirana, kureva kuti, yero inogona kuderedza pepuru, uye pepuru inogona kuderedza yero;
Bhuruu rinoenderana neorenji, kureva kuti, bhuruu rinogona kuderedza orenji, uye orenji rinogona kuderedza bhuruu;
3. Zvinokosha zvemavara
Vanhuwo zvavo vanoti ruvara 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,iyo inotsanangura kudzika kweruvara.
4. Nheyo huru dzekufananidza mavara
Kazhinji musashandise marudzi anopfuura matatu ependi yemavara. Mavara akasiyana-siyana epakati (ndiko kuti, mavara ane mavara akasiyana) anogona kuwanikwa nekusanganisa mavara matsvuku, eyero, nebhuruu mune imwe chiyero. Kubva paruvara rwekutanga, kuwedzera chena, unogona kuwana mavara ane saturation yakasiyana (ndiko kuti, mavara ane mavara akasiyana). Kubva paruvara rwekutanga, kuwedzera dema, unogona kuwana mavara ane chiedza chakasiyana (ndiko kuti, mavara ane kupenya kwakasiyana).
5. Unyanzvi hwekutanga hwekufananidza mavara
Kusanganisa uye kufananidza mavara emapendi kunotevera musimboti wekubvisa mavara, mavara matatu makuru itsvuku, yero, nebhuruu, uye mavara awo anowirirana igirini, pepuru, neorenji. Mavara anonzi anowirirana mavara maviri akasanganiswa muchikamu chakati kuti awane chiedza cheruvara ruchena, 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 akasanganiswa muchikamu chakati kuti awane chiedza cheruvara ruchena, 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 waenzanisa mavara, tanga waona kuti ruvara rwunosanganiswa rwuri papi mumufananidzo zvichienderana nemufananidzo unotevera, wobva wasarudza mavara maviri akafanana ekusanganisa nechikamu chakati. Shandisa ndiro yebhodhoro regirazi kana chidimbu chebasa chinofanira kupfapfaidzwa kuti chienzaniswe nemavara (ukobvu hwe substrate, bhodhoro regirazi remunyu wesodium uye bhodhoro regirazi remunyu wecalcium zvicharatidza mhedzisiro dzakasiyana). Paunosanganisa mavara, tanga wawedzera ruvara rukuru, wobva washandisa ruvara rwakasimba serubatsiro, wedzera zvishoma nezvishoma uye nguva nenguva woramba uchikurunga, kuti uone kuchinja kweruvara chero nguva, uye tora muenzaniso nekupukuta, kukwesha, kupfapfaidza kana kunamira pamuenzaniso wakachena. Mushure mekunge ruvara rwagadzikana, enzanisa ruvara nemuenzaniso wekutanga. Mukuita kwese kwekufananidza mavara, nheyo yekuti "kubva pakadzika kusvika parima" inofanira kunzwisiswa.
