Umthi Esitalini: iindlela kungamampunge kunye neempawu

Kuba baninzi umbuzo umbuzo, oko kuthetha ntoni na "utsho womelele." It esixhotyiswe ngokukodwa ngezinto ngayo yaye iimpawu ezongezelelweyo zokuhombisa nokuqina kwayo, ipateni yendalo kuhlala ingatshintshanga.

incazelo

Olu hlobo lonyango kwakhona badla ngokuba ulondolozo, kufanele, ekubeni umsebenzi ophambili ubekwa ukulondoloza nokuphucula umgangatho kweenkuni. Ukufumana yoko enjalo singavuselelwa nokusetyenziswa material ekhethekileyo kuwuzalisileyo pores kunye lukhuni. Le emahlamvini, Polymer kunye nepeyinti nemixube,-oyile ezahlukeneyo ezifunyenwe kakhulu ngokubanzi.

umthi Esitalini lubamba ngokupheleleyo ubume imibala kwaye kuthatha ithoni omtsha kungekuphela komhlaba kodwa kulo lonke isakhiwo. Kukho iinketho ezahlukeneyo luyawudyobha ukusuka zendalo imibala eqaqambileyo.

iimpawu

Ukuze ufumane iziphumo ezizizo kufuna elungiselela kunye nokubambelela ngenyameko yonke imithetho. Ngokuzimeleyo akulula ukwenza inqanaba ezinqwenelekayo koxinzelelo, emoyeni kwaye kubekho ulawulo lobushushu ethile kodwa ukugcinwa bengasaphili ngaphandle kwezi meko.

Okokuqala, kufuneka sithathe lo workpiece ngokufanelekileyo. Kwiimeko ezininzi, ukuba ukhonza izinto kunye modulations ezintle kunye nesakhiwo, oko kufuneka ukuze hardwoods ezahlukeneyo zezi: nezompleyini, Elm, maple kunye ezinde.

umthi Esitalini unawo mihlaba ilandelayo:

• yobulukhuni;
• mninzi;
• ukumelana oyile ezahlukeneyo kunye izinyibilikisi eziphilayo;
• iimpawu ethile emihle;
• umthi Esitalini igcina iipropati kwanaxa itshiswe emlilweni.

ukumitha

Eli nyathelo ingaqhutywa ngeendlela ezahlukeneyo:

• Ukuzinziswa yengcinezelo ophezulu. Ukulungiselela le njongo, isikhongozeli ekhethiweyo izaliswe sisincoko apho preform egxile. Ngoko ke isikhongozeli ibekwe indawana ekhethekile apho koxinzelelo yenziwa. umgaqo ifuthe kukuba umoya betekisi ukusuka workpiece, kwaye isithuba esingenamntu uzele ngodaka.
• inkqubo cleaner. Le nto ufakwa kwigumbi apho umoya kamva umpontshelwa ngaphandle, yaye njengoko kusa- ukusuka workpiece. Ngoko ke isisombululo ngokulula angcolise ubungangamsha emithanjeni kunye pores engenanto.
• Hot ukumitha. Le iinkuni iphekwe okanye zifakwe emanzini imixube ezizodwa. Luphawulwa indlela ayisebenzisayo yokunyibilika ngokutshisa, ukuze kwandiswe kakhulu le flowability kunye wazalisa umgangatho.
• ukumitha Cold yenye kangangoko ukuba workpieces ezibhityileyo.

polymerization

Le nkqubo iphela inkqubo kunye lukhutshwe yaphuse imveliso kwi obushushu ezifunekayo. iinkuni sezwe ephatha ngayo ukufumana iimpawu ezintsha, enika ukufana kunye nezinto polymeric, njengoko itshintsha umbala ubunzima baso. Ngoko ke umgangatho imicu ayafana, bona Ukongezelela ukulungisa isisombululo ezisetyenziswa xa kusenziwa, ngaloo ndlela eyakha imbonakalo entle kwaye ocacileyo yonke preform. Kubalulekile ukuqaphela ukuba ezinye izixhobo ezisetyenziswa kwesi sigaba, samozatverdevaniya impahla ezahlukeneyo.

Indlela ukuzinzisa umthi imela yokubamba

Izinto ezenziwayo ngokufanelekileyo ukudala iimveliso ezahlukeneyo ezenziwe ngezandla. Oku ezininzi eziqhele ukusetyenziswa ekwenziweni izibambo olupheleleyo iintshengece.

Enye Ukuqamba lithandwa ekulondolozeni "Anakrol-90", kugalela ingongoma apho ngaphakathi degrees 90. Ngokuba imisebenzi ifuna inkqubo lwepolitiki, ukuba zingenziwa macandelo alandelayo: gauge koxinzelelo, isiguquli, impompo lwepolitiki, inani iityhubhu, imigqomo yeplastiki eyayinkulu enkulu. Emva koko, imithi ngcono womile eontini ekhethekileyo, kunye ukungabikho kwalo Ungasebenzisa Aerogrill okanye oveni.

Umama Ukutyeba ezisetyenziswayo kufuneka ingadluli 3-4 cm, kuyimfuneko ukuba ezikumgangatho ophezulu ukumitha le preform na.

Incence yomthi obekwe kwisingxobo kunye nesisombululo, kanti kufuneka ngokupheleleyo egubungele anakrolom. Zidle idaliwe de kube ngoko, kude kungabikho moya amaqamza phandle.

Ngaphezu koko, uxinzelelo oluphezulu idaliwe, i-pre-kuqulunqo kufuneka ume kangangesiqingatha seyure. inqanaba xi mayifike ukuya ku 2-4 ATM, kufuneka ukusebenzisa impompo kunye isiguquli. Le nkqubo kufuneka iphindwe emva kwemizuzu engama-40. Zenzo zenziwe logama nje imveliso akuthethi Nditshonile emanzini. Kulo mzekelo, akukho mathandabuzo a preform qualitative buzane.

Ngoko umthi esitalini ngezandla zakhe Oku ngokupheleleyo womile kwiqondo lobushushu ngeedegree ezimalunga ne-100. Emva kufuneka bikho amabala ekrwada. unyango olunjalo kunika izinto ache yaye kuphuculwa ukusebenza ipolishi. Iipateni ithinti engesiso zingafumaneka ngokongeza ngombala ezahlukeneyo ekwakhiweni. Kwakhona namhlanje, lungafumaneka kwi yokuthengisa izisombululo esele zenziwe kunye ezahlukeneyo abangasekhoyo.

Ukusebenzisa epoxy resin

Le ndlela ezifanayo ulondolozo kunye anakrola, umahluko ophambili ilele kwaso indawo i nentlaka epoxy ugalelwe utywala. Le yokugqibela isetyenziselwa ukuphucula umgangatho ukumitha. Ukusebenza resin kufuna umonde, elide kangaka njengoko polymerized kurhulumente oyifunayo. Kukho izisombululo ezahlukeneyo ngokusekelwe nentlaka epoxy. Likriwa etheza iinkuni evela ekusetyenzisweni ubume ezinjalo nge iqondo eliphezulu fluidity, ebonakala ngu iimpawu kakhulu.
